QUESTION 7 A trolley of mass 400 kg moves along a frictionless track from left to...
Block 1, of mass m1 = 3.50 kg , moves along a frictionless air track with speed v1 = 11.0 m/s . It collides with block 2, of mass m2 = 43.0 kg , which was initially at rest. The blocks stick together after the collision. What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?
Block 1, of mass m1 = 8.90 kg , moves along a frictionless air track with speed v1 = 31.0 m/s . It collides with block 2, of mass m2 = 15.0 kg , which was initially at rest. The blocks stick together after the collision. (Figure 1) What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?
Block 1, of mass m1 = 9.10 kg , moves along a frictionless air track with speed v1 = 27.0 m/s . It collides with block 2, of mass m2 = 13.0 kg , which was initially at rest. The blocks stick together after the collision. What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision? Express your answer numerically in joules. Before collision: m2 After collision:
Block 1, of mass m1 = 1.10 kg , moves along a frictionless air track with speed v1 = 29.0 m/s . It collides with block 2, of mass m2 = 45.0 kg , which was initially at rest.

Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.116 kg, initially moves to the right at a speed of 5.20 m/s, while the second block, of mass 0.232 kg, is initially to the left of the first block and moving to the right at 7.30 m/s. Find the final velocities of the blocks, assuming the collision is elastic. Velocity of the .116 kg block to the right: Velocity fo the .232...

Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.105 kg, initially moves to the right at a speed of 4.50 m/s, while the second block, of mass 0.210 kg, is initially to the left of the first block and moving to the right at 7.10 m/s. Find the final velocities of the blocks, assuming the collision is elastic. velocity of the 0.105 kg block = velocity of the 0.210 kg block...
Consider a frictionless track as shown in the figure below. A block of mass m1 = 5.65 kg is released from A. It makes a head-on elastic collision at B with a block of mass m2 = 20.0 kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision.Two masses are shown on a frictionless wooden track. The left part of the track curves downward from left to right, starting from an almost-vertical slope and then decreasing in...
Two air track carts move along an air track towards each other. Cart A has a mass of 450 g and moves toward the right with a speed of 0.850 m/s. Cart B has a mass of 270 g and moves toward the left with a speed of 1.12 m/s. What is the total momentum of the two-cart system? Give your answer in kg m/s, to three significant firgures. Your Answer: Answer units
