You push a box of mass 19.1 kg with your car up to an icy hill slope of irregular shape to a height 5.9 m. The box has a speed 12.9 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before sliding into a box larger box of mass 13 kg. The boxes then fall off a sheer cliff together to the ground (with no drag).

a) What is the velocity of the pair just before hitting the ground? {coordinate form}

V = ________y, ________z

b) What is the velocity of the pair just before hitting the ground? {vector form}

V = ________ (_________y, __________z)

c) What is the path basis just before impact?

t = _________x + _________y + _________z

n = _________x + __________y + _________z

b = _________x + __________y + _________z

You push a box of mass 17.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 11.8 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 12 kg. The boxes then fall off a sheer cliff individually to the...

A 1150 kg car drives up a hill that is 15.7 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is −2.91×105 J ; the work done by the engine is 6.74×105 J . Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
