A 55-kg crate is pulled horizontally 7.0 m across the floor by a force F whose magnitude is 160 N. The force F is parallel to the displacement of the box. The coefficient of kinetic friction is 0.25.
A. If the crate starts from rest, use the work-energy theorem to find the velocity of the crate after it has moved 7.0 m horizontally.
B. After the crate has moved 7.0 m horizontally, the external force F no longer acts on it. The crate slides up a ramp (with the same coefficient of kinetic friction) that rises 20.0º above the horizontal. How high above the ground does the crate get before it stops moving and slides back down the ramp?
please write out out clear answers and how you got answers step by step (such as showing numbers/variables you add or carry over or cancel etc.) this is a very confusing problems for me thank you.
