A baseball with mass of 0.16 kg is batted into the air. Its initial speed is 35.0 m/s, directed at an angle 39 degrees above the horizontal. If the height of the ball when it was struck by the bat is 35 cm, how high off the ground (in m) is the ball when it reaches the highest point in its trajectory?

In a jump serve in volleyball, the server throws the ball into the air and strikes it with his open hand from a position 9 m behind the net. An athletic player may be able to hit it when the bottom of the ball is 3 m above the ground. Without aerodynamic effects, a horizontally hit serve will never work—it will go into the net or go too far and out of bounds. How much time does it take for the ball to fall to the height of the top of the net (which is 2.41 m above the floor)? Also, calculate the minimum launch speed for the ball to make it over the net. Round the final answer to two decimal places. What is the range of the ball struck horizontally at this speed? Round the final answer to one decimal place. Do you think that putting topspin on the serve might improve the serve? The “sky serve” is intended to land on the opponent’s side at a nearly straight-down trajectory. If this serve were a sky serve, launched at the same speed, but at the nearly vertical angle of 85°, would it…

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?

A baseball is hit from ground level with a speed of 50.0 m/s and at an angle of 53.10.Take g=10m/s2. At what two times is the baseball 35 m above the ground?

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.47 m/s at an angle of 83.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?

In the figure, a stone is projected at a cliff of height h with an initial speed of 49.0 m/s directed at an angle e0 = 53.0° above the horizontal. The stone strikes at A, 5.89 s after launching. Find (a) the height h of the cliff, (b) the speed of the stone just before impact at A, and (c) the maximum height H reached above the ground. (a) Number i Units (b) Number Units (c) Number Units

A guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.

A basketball player shoots toward a basket 6.1 m away and 3.0 m above the floor. If the ball is released 1.8 m above the floor at an angle of 60° above the horizontal, what must the initial speed be if it were to go through the basket?

A basketball player shoots toward a basket 6.2 m away and 3.0 m above the floor. If the ball is released 1.9 m above the floor at an angle of 48 degrees above the horizontal, what must the initial speed be if it were to go through the basket?

A rocket is launched at ground level with an initial speed of 189 ft/s, at an angle of 34° above the horizontal. It strikes a mark above the ground 2.4 seconds later.What is the vertical distance, in feet, from where the rocket was launched to where it lands?
