I need help in this physics question
Two masses mA = m and mB = 4m are suspended from the ceiling by strings of equal length. Mass A is released from rest from a height h, and collides with mass B, which is initially at rest. The collision is elastic. What is the maximum height attained by mass B after the collision (as a function of h)?

Two masses, mA = 34.0 kg and mB = 40.0 kg , are connected by a
rope that hangs over a pulley (as in the figure (Figure 1)). The
center of the pulley is hollowed out so that you may assume all the
mass of the pulley is in the rim. The radius of the pulley is 0.381
m and the mass of the pulley is 3.10 kg . Initially mA is on the
ground and mB rests 2.50 m...

Two masses, Ma= 35.0kg and Mb =
40.0 kg, are connected by a rope that hangs over a pulley (as in
the figure ). The pulley is a uniform cylinder of radius 0.381m and
mass 3.4kg . Initially Ma is on the ground and Mb rests 2.3m above
the ground.
If the system is released, use conservation of energy to determine
the speed of just before it strikes the ground. Assume the pulley
bearing is frictionless.

A mass m is dropped from rest from a height h above the left hand side of a frictionless bowl where it meets the side of the bowl exactly after falling h and starts to slide down the side of the bowl with some initial velocity where it then collides with a 4m mass sitting at the bottom. The 4m mass makes it exactly up to the rim of the bowl on the right hand side and the m mass...

2. (25 pts.) A simple pendulum of length L = 1.0 m, with a mass mp = 5.0 kg at the end, is held at a 90° angle and released from rest. There are also two blocks, A and B with masses ma = 10 kg and mb = 15 kg, at rest on a horizon- tal, frictionless surface. After the release, the pendulum collides elastically with block A, which in turn collides completely/perfectly inelastically with block B. a. Immediately...

Billiard ball A of mass mA = 0.130 kg moving with speed vA = 2.95 m/s strikes ball B, initially at rest, of mass mB = 0.150 kg . As a result of the collision, ball A is deflected off at an angle of 29.5 ∘ with a speed vA1 = 2.25 m/s Solve these equations for the speed, vB1, of ball B. Do not assume the collision is elastic.

Two objects of masses m and 4m are moving toward each other along the x-axis with the same initial speed v0 = 460 m/s. The object with mass m is traveling to the left, and the object with mass 4m is traveling to the right. They undergo an elastic glancing collision such that m is moving downward after the collision at a right angle from its initial direction.
