Starting from rest, a person pushes a large bin of mass 50.0 kg with a constant force of 160 N. While the person pushes the bin, the coefficient of kinetic coefficient between the bin and the ground is 0.30. The person pushes the bin for 19 m.
a) What is the speed of the bin after 19 m of being pushed?
b) What is the work done on the bin? Identify what does the work for any values you state.
c) What is the change in the bin’s kinetic energy?
d) State whether this is an isolated system. If there are any amounts of energy not accounted for in parts b and c, use the work-energy theorem to identify what it is and how much.
a) If the car is moving with a speed of 16 m/s at the top of the hill, find the normal force acting on the car.
b) What g-force does the car experience?
c) Determine the maximum speed the car can have at the top of the hill and still remain on the road

A ball of clay with a mass of 4.0 kg, starting from rest, falls
from a height of 0.20 m above a block with mass 1.0 kg that rests
on top of a spring with spring constant 90 N/m. The block then
sticks to the block and the system undergoes simple harmonic
motion. Please submit your answers to the following questions on a
separate sheet of paper (or multiple sheets of paper).
i. Write the formulas for the position, velocity,...

A 91 kg crate, starting from rest, is pulled across a floor with
a constant horizontal force of 340 N . For the first 15m the floor
is frictionless, and for the next 15 m the coefficient of friction
is 0.22.

A coin and a ring have the same mass and radius. Starting from
rest and the same height, they roll down the same incline. In other
words, they both start with the same gravitational potential
energy. Which one of the following statements is true about the
coin and ring when they reach the bottom of the incline?
