An artillery shell is fired with an initial velocity of 300 m/s at 52.0° above the horizontal. To clear an avalanche, it explodes on a mountainside 40.5 s after firing. What are the x- and y-coordinates of the shell where it explodes, relative to its firing point? x =   m y =   m

An artillery shell is fired with an initial velocity of 300 m/s at 56.5° above the horizontal. To clear an avalanche, it explodes on a mountainside 40.0 s after firing. What are the x and y components of the shell where it explodes, relative to its firing point? X = m

An artillery shell is fired with an initial velocity of 300 m/s at 54.5° above the horizontal. To clear an avalanche, it explodes on a mountainside 34.0 s after firing. What are the x- and y-coordinates of the shell where it explodes, relative to its firing point? x=? y=?

During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed v0 = 42 m/s at an angle θ = 43° above horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Air resistance may be ignored throughout this problem. a.)Express the magnitude of the ball’s initial horizontal velocity v0x in terms of v0 and θ.  b.)Express the magnitude of the ball’s initial vertical velocity v0y in terms of v0 and θ.  c.)Find the ball’s maximum vertical height hmax in meters above the ground.

Two identical objects with the same initial speed collide and stick together. If the composite object moves with half the initial speed of either object, what was the angle between the initial velocities? 20° O 30° 450 60° 120°

A baseball is thrown from an outfielder to the second baseman on a level field. The ball is in the air for a time At = 3.50 s and travels a horizontal distance of 92.0 m %3D before being caught at the same height it was thrown from. Ignore air resistance. a) What are the x- and y-components of the ball's initial velocity? b) What is the maximum height of the ball? c) When is the ball traveling at an angle of 0 = -26.0°?

A 2.00-m-tall basketball player is standing on the floor 10.0 m from the basket, as in the figure below. If he shoots the ball at a 40.0° angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket is 3.05 m. m/s 40.0 2,00 3.05 m 10.0 m

Q1-A 2.0 meter tall basketball player is standing on the floor a distance from the basket. He shoots the ball at an angle of 23 degrees above the horizontal with a speed of 9.6 m/s and makes the shot. If the ball goes in the hoop at 5 seconds, what is the height of the hoop?

A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 650 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.023 m below the center. What is the horizontal distance between the end of the rifle and the bull's-eye?

On a spacecraft, two engines are turned on for 908 s at a moment when the velocity of the craft has x and y components of v0x = 5150 m/s and v0y = 6290 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 2.85 x 106 m and y = 4.72 x 106 m. Find the (a) x and (b) y components of the craft's acceleration
