During a tennis match, a player serves the ball at 23.6 m/s, with the center of the ball leaving the racquet horizontally 2.37 m above the court surface. The net is 12 m away and 0.90 m high.When the ball reaches the net, (a) does the ball clear it and (b) what is the distance between the center of the ball and the top of the net? Suppose that, instead, the ball is served as before but now it leaves the racquet at 5.00° below the horizontal.When the ball reaches the net, (c) does the ball clear it and (d) what now is the distance between the center of the ball and the top of the net?

A playground is on the flat roof of a city school, h = 6.00 m above the street below (see figure). The vertical wall of the building is h = 7.50 m high, to form a 1.5-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 0 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. (No Response) m/s (b) Find the vertical distance by which the ball clears the wall. (No Response) m (c) Find the horizontal distance from the wall to the point on the roof where the ball lands. (No Response) m

During a tennis match, a player serves the ball at 23.6 m/s, with the center of the ball leaving the racquet horizontally 2.60 m above the court surface. The net is 12.0 m away and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net? (b) Suppose that, instead, the ball is served as before but now it leaves the racquet at 5.00° below the horizontal. When the ball reaches the net, what now is the distance between the center of the ball and the top of the net? Enter a positive number if the ball clears the net. If the ball does not clear the net, your answer should be a negative number. Use g=9.81 m/s?.   Please explain step by step with drawing.. thank you.

A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 700 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.021 m below the center. What is the horizontal distance between the end of the rifle and the bull's-eye?

The initial speed of the ball is v0 = 22.2 m/s, the angle the ball is hit at is θ = 43o, and g = 8.4.   How far away does the ball hit the ground?

Two friends are playing catch, indoors, with a baseball, where the ceiling height is 6.15mm. The first friend releases the ball at a height of 3.15mm with a velocity of 21.8m/sm/s, and the second friend catches it at the same height. Neglect the diameter of the baseball. What is the maximum vertical component of the velocity, in meters per second, such that the baseball does not hit the ceiling?

A playground is on the flat roof of a city school, hb = 4.60 m above the street below. The vertical wall of the building is h = 6.10 m high, to form a 1.5-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of ? = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. (b) Find the vertical distance by which the ball clears the wall. (c) Find the horizontal distance from the wall to the point on the roof where the ball lands.

A playground is on the flat roof of a city school, h, = 6.70 m above the street below (see figure). The vertical wall of the building is h = 7.90 m high, to form a 1.2-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 0 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. 18.0 V m/s (b) Find the vertical distance by which the ball clears the wall. 0.32 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m (c) Find the horizontal distance from the wall to the point on the roof where the ball lands. 2.14 Your response differs from the correct answer by more than 10%. Double check your calculations. m

Serving at a speed of 170 km/h, a tennis player hits the ball at a height of 2.5 m and an angle below the horizontal. The base line is 11.9 m from the net, which is 0.91 m high. What is the angle such that the ball just crosses the net? Will the ball land in the service box, whose service line is 6.40 m from the net?

During a tennis match, a player serves the ball at 28.3 m/s, with the center of the ball leaving the racquet horizontally 2.57 m above the court surface. The net is 12.0 m away and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net? (b) Suppose that, instead, the ball is served as before but now it leaves the racquet at 5.00° below the horizontal. When the ball reaches the net, what now is the distance between the center of the ball and the top of the net? Enter a positive number if the ball clears the net. If the ball does not clear the net, your answer should be a negative number. Use g=9.81 m/s². (a) Number (b) Number Units Units
