A truck of mass 9M is moving at a speed v = 15 km/h when it collides head-on with a parked car of mass M. Spring mounted bumpers ensure that the collision is essentially elastic. Find the final velocities of each vehicle. Repeat for the case of the car moving at speed v= 15km/h and colliding with the stationary truck. What fraction of the incident vehicle’s kinetic energy is transferred in each case?

A bullet of mass m and speed v is fired at, hits and passes completely through a pendulum bob of mass M on the end of a stiff rod of negligible mass and length L. The bullet emerges with a speed of v/2 and the pendulum bob just makes it over the top of the trajectory without falling backward in its circular path. Determine an expression for the minimum initial speed the bullet must have...

A bullet of mass m is fired with a speed v at a wooden block of
mass M which is hanging from the ceiling. The block swings upward
and reaches a maximum height of h. By measuring h, we can find the
initial speed of the bullet v.
a.) Let's say at time t = t0 the bullet has not yet
hit the block. At time t=t1 the bullet/block system is
lodged in the block and the bullet/block system is...

A rubber bullet of mass m = 0.025 k g m=0.025kg traveling at velocity v 0 = 50 m / s v 0 =50m/s hits an iron block of mass M = 15 k g M=15kg initially hanging at rest from a massless rope. After the collision, the bullet bounced straight back at a velocity of v 1 = 35 m / s v 1 =35m/s. The effect of gravity on the bullet alone can be ignored. To...

1. A bullet of mass m -25.0 g is fired into a stationary block of mass m, -4.00 kg, which is suspended on a rope, as shown below. The bullet is initially traveling with velocity v. - 400 m/s, passes through the block and emerges with a final velocity horizontally Immediately after the impact the block travels upward with a velocity of 2.00 m's and reaches a vertical height, h before coming to rest. Determine the maximum height the block...

A truck with a mass of 1510 kg and moving with a speed of 14.5 m/s rear-ends a 671 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.
