A couple of boxes with different masses, 5.70 kg and 1.60 kg , hang 0.800 m above the floor from the ends of a cord 7.30 m long passing over a frictionless pulley. The boxes are released from rest with the heavy box falling and lifting up the light box.Find the maximum height above the floor reached by the 1.60 kg box.

Two boxes with masses m1=5.0 kg and m2=3.0 kg are connected by a
massless rope, which is put over a massless, frictionless pulley.
The coefficient of kinetic friction between the incline and the
boxes is 0.12 and the coefficient of static friction between the
incline and the boxes is 0.25.The angles of the inclines with
respect to the horizontal are ?=45** and ?2=30**. Use 9.8 m/s^2 for
gravity and assume the incline is fixed in space.

A landing craft with mass 1.22×104 kg is in a circular orbit a
distance 5.70×105 m above the surface of a planet. The period of
the orbit is 5600 s . The astronauts in the lander measure the
diameter of the planet to be 9.80×106 m . The lander sets down at
the north pole of the planet.
A. What is the weight w of an astronaut of mass 86.0 kg as he
steps out onto the planet's surface?

Imagine two carts with different masses colliding (m1 = 2.0 kg,
m2 = 1.0 kg). If cart one is initially moving at 10 m/s and the
other cart is stationary, calculate the final speed of each mass
after they have a 100% elastic collision. Please show all work!
