Shown in the figure is a ball with mass, m, and initial speed, v, hitting the ground at an angle. The ball bounces off the ground and leaves with the same speed as it initially had and makes an angle with the ground as shown in the figure. What is the impulse by the ground on the ball in unit vector notation? OO + 2mv cos(0) û O0+ 0 g 2mv cos(O) € + 2mv sin(0) ☺ 00 € +...
A 4.50-kg steel ball strikes a wall with a speed of 7.0 m/s at an angle of θ = 60.0° with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.) Fx = N Fy = N
A tennis ball of mass m = 0.057 kg and speed v = 18 m/s strikes a wall at a 45∘ angle and rebounds with the same speed at 45∘ What is the magnitude of the impulse given to the ball?
rks) A 15kg solid ball strike a wall with a speed 20m/s at an angle 60° with the surface. It bounces off with the is in contact with the wall for 0.55s, what is the impulse that the ball experience, and force direction and magnitude exerted on the ball by the wall. speed of 15 m/s and the same angle to the vertical direction 60°.

A 2.92-kg steel ball strokes a massive wall at 10.0 m/s at an angle of theta = 60.0 degree with the plane of the wall. It bounces off the wall with the same speed and angle. If the ball is in contract with the wall for 0.184 s, what is the average force existed by the wall on the ball?
A 100 gm ball strikes a wall at 600 (with respect to the wall) with a velocity of 8 m/sec and bounces back with three forth of its speed at the same angle with respect to the wall. If the ball remains in contact for 0.1 sec, what is the force? A 100 gm ball strikes a wall at 60° (with respect to the wall) with a velocity of 8 m/sec and bounces back with three forth of its speed...
A 250 g ball with a speed of 5.0 m/s strikes a vertical wall at an angle of 30° to the surface and rebounds at the same angle with the same speed.. The ball is in contact with the wall for 10 ms. What is the impulse on the ball? Choose correct answers: 1.25 N s 2.5 N s 4.33 N s 5.0 N s
A 3.6-kg steel ball traveling at 8.0 m/s hits a wall at an angle of ? = 61.0o as shown in the figure. It bounces off the wall with the same speed and same angle. If the ball was in contact with the wall for 0.14 seconds, what was the magnitude of the average force exerted on the ball by the wall?
