rks) A 15kg solid ball strike a wall with a speed 20m/s at an angle 60°...
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 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?
5. A ball of mass m strikes a massive wall at speed v, at an angle 0 with the normal to the wall. It bounces off with the same speed and angle. If the ball is in contact with the wall for a time t, what is the magnitude of the impulse applied to the ball by the wall? A. 2mv. B. 2mv, sino OL→î C. 2mv, cos e D. mv, tan o E. mv./t
You throw a 0.350 kg tennis ball horizontally toward a wall. The speed of the ball is 12 m/s before it hits the wall, and it bounces back with the same speed of 12 m/s. If the ball remains in contact with the wall during this collision for 0.025 s, what is the magnitude of the average force exerted on the ball?
A ball with an initial velocity of 10 m/s moves at an angle 60º above the + x -direction. The ball hits a vertical wall and bounces off so that it is moving 60º above the − x -direction with the same speed. What is the impulse delivered by the wall?
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 ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 65.5° above the horizontal, moving in the opposite direction with the same speed. See the figure. What was the magnitude of the impulse delivered by the wall, in kilogram meters per second?
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 .15kg rubber ball is bounced off a wall. Before hitting the wall, the ball moves toward the wall at a velocity of (-8,1) m/s. If the wall exerts an average force of 300N acting in the x-direction for 0.006s then what is the final velocity of the ball after leaving the wall?
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...
