3) A 4.0 kg ball going right at 7.0 m/s strikes a stationary 6.5 kg ball....
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 1.0-kg ball with a speed of 3.0 m/s strikes a 2.0-kg stationary ball. The collision is completely inelastic. (a) Calculate the speed of the balls after collision. (b) Calculate the total kinetic energy change during the collision
A 6 kg bowling ball rolling at 5 m/s strikes a stationary 4 kg bowling ball. If ball #1 is moving forward at 2 m/s after the collision, what is the speed and direction of ball #2? What is the impulse of the system? If the collision last for .5 seconds, how much force is exerted?
A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.20 m/s, at an angle of +30.0
y A 2 kg ball moving to the right along the x-axis at 5.0 m/s collides with a stationary 4.0 kg ball After the collision, the 2 kg ball is seen moving at 370 above the x-axis and the 4 kg ball is moving at 60° below the x-axis as shown below in the diagram. a) Find the speed of the each ball after the collision. b) Is this collision elastic or inelastic? Explain your answer with appropriate computations. y-...
A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, ball of the same mass. After the collision, the first ball moves at 5.25 m/s, at an angle of 299 with respect to the (a) Find the velocity (magnitude and direction) of the second ball after collsion. (Enter the direction with respect to the original line of motion. Incude the sign of your sign answer. Consider the m/s O inelastic elastie Need...
A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.94 m/s at an angle of 34.5° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. What is the magnitude of the velocity and the direction o counter-clockwise from the original direction of motion?
a 5 kg steel ball moving 8 m/s, collides off center with a stationary 2 kg ball and then the 2 kg ball moves off at 10 m/s, find the angle the 5 kg ball moves off at. Then the find the angle that the 2 kg ball moves of at.
A 0.25 kg ball moving at a speed of 3 m/s, along the positive x-axis, strikes a stationary horizontal ball of mass 0.30 kg. (a) If the collision is perfectly inelastic, what is the velocity and direction of the balls? (b) If the second ball moves at a rate of 1 m/s towards the positive x-axis, what is the velocity and direction of the first 2. ball after collision?
A billiard ball moving at a speed of 7.95 m/s strikes an identical stationary ball a glancing blow. After the collision, one ball is found to be moving at a speed of 1.80 m/s in a direction making a 59.5 ° with the original line of motion. What is the speed of the other ball? At what angle is it moving? Give your answer in degrees. (Hint: use conservation of linear momentum)
