A truck with a mass of 1300 kg and moving with a speed of 12.0 m/s rear-ends a 843 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second A 61.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped...
Suppose a 0.350 kg ball is thrown at 20.0 m/s to a motionless person standing on ice who catches it with an outstretched arm. Calculate the final linear velocity (in m/s) of the person, given his mass is 65.0 kg. (Already have, 0.107 m/s) What is his angular velocity (in rad/s) if each arm is 4.00 kg? You may treat the ball as a point mass and treat the person's arms as uniform rods (each has a length of 0.800...
of mass 1.00 kg moves East at 5.00 mts collides with another ball, of mass 2.00 kg, moving Ms. After the collision, the 2.00 ke mass moves at a velocity of 4.00 m/s East. What is the the other ball? Does this collision conserve mechanical energy (and explain why?
QUESTION 4 15 points Save A truck of mass 5m traveling with a speed v collides with a stationary car of mass m.

Suppose a 0.390 kg ball is thrown at 17.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure below. (a) Calculate the final linear velocity (in m/s) of the person, given his mass is 90.0 kg x m/s 07 (b) What is his angular velocity (in rad/s) if each arm is 3.00 kg? You may treat the ball as a point mass and treat the person's arms as uniform...
A ball with a mass of 0.615 kg is initially at rest. It is struck by a second ball having a mass of 0.410 kg , initially moving with a velocity of 0.235 m/s toward the right along the x axis. After the collision, the 0.410 kg ball has a velocity of 0.200 m/s at an angle of 36.8 ∘ above the x axis in the first quadrant. Both balls move on a frictionless, horizontal surface. What is the magnitude...
A billiard ball with a mass of 0.15 kg is moving with a velocity of < 5, 0, 0 > m/s. It collides with a 2nd billiard ball of mass 0.20 kg initially moving at < -7, 0, 0 > m/s. After the collision, you observe the 2nd billiard ball moving at < 0.13, 0, 0 > m/s. a) What is the velocity of the 0.15 kg billiard ball after the collision? b) What is the vector change in momentum...
Question 2 O out of 3 points A 2.5 kg ball moving at 4.2 m/s collides with a 2.5 kg stationary ball in a perfectly elastic collision. What is the velocity of the second ball after the collision? Selected Answer: 4.2 m/s Answers: 4.2 m/s None of these 8.4 ms 1.2 m/s 4.8 m/s
A ball of mass 0.442 kg moving east (+x direction) with a speed of 3.72 m/s collides head-on with a 0.221 kg ball at rest. Assume that the collision is perfectly elastic. a) What is be the speed of the 0.442-kg ball after the collision? b) What is be the direction of the velocity of the 0.442-kg ball after the collision? to the east or to the west c)What is the speed of the 0.221-kg ball after the collision? d)What...
