A mass, m, with speed, v, undergoes a perfectly elastic collision with an initially stationary mass, M, as shown in the picture. What is the ratio of the two masses, m/M if after the collision, m and M have the same speed, V, but opposite velocities?

In what way can you tell if linear momentum and/or k.E are conserved in a 1D collision? Would the   impulse on both objects be the same in a collision?

A bumper cap "A" (mass of A = 140kg) with a velocity of 15 km/hr hits a another car "B" (mass of B = 160kg) which was immobile before impact. The collision is perfectly elastic & the frictions are considered negligible. Calculate the time at which the bumper cars are 2m apart from each other after the collision

A train car with a mass of 200kg is moving down the track at 10m/sec. it its another train car with mass 250kg which is moving in the same direction with speed of 6m/sec. the two cars hit and lock together, what would the speed be after collision?

A small block of mass M is released from rest at the top of the curved frictionless ramp shown in the figure. The block slides down the ramp and is moving with a speed of 3.50 m/s when it collides with a larger block mass 1.5M at rest at the bottom of the incline. The larger block moves to the right with a speed of 2m/s immediately after the collision. Express your answer in speed of the small block after the collision in terms of the given quantities and fundamental constants. ... 1.5M 2 M - 1.50 A V small block M ЗМ— 1.50M в) V small block M 3.50 (m/s) M-3(m/s)M © v V small block M 3.50 (m/s) M- 1.50(m/s) M D V small block M

A fast car is speeding down a road with a velocity of v. It collides with a truck moving in the opposite direction that has a mass that is four times that of the fast car. They are both moving at the same speed. If the collision is elastic, then what are both of the vehicles velocities given as multiples of v.

Problem 8 A 1D perfectly inelastic collision occurs between two masses m and M. If the mass m is initially moving right at a speed of vo and the other mass it at rest, what is the ratio of the total kinetic energy after the collision to the original kinetic energy?

Let's assume a perfectly elastic collision between a golf club (mass of 250 gr) and a golf ball (mass of 46 gr). If the club hits the ball at a speed of 45 m/sec what will be the speed of the ball after the impact?  What happens if the mass of the club is doubled?

A 3kg body moving at 4m/s makes an elastic collision with a stationary body of mass 2kg

A railroad car of mass 2500 kg is moving with a speed of 4 m/s. It collides and couples with another railroadcar of the same mass as it moves in the same direction with an initial speed of 2 m/s.a) What is the speed of the two cars after the collision? ?b) If the collision happened within 0.02s, how big is the force impacted on each car?
