A 100 kg crate is pushed along a concrete surface by a forklift exerting a constant 1000 N force. The frictional force between the crate and the concrete is a constant 600 N. The crate is initially stationary and is pushed for a distance of 10 m.   What is the kinetic energy of the crate after the push? At what speed is the crate moving after the push?

Question

A 100 kg crate is pushed along a concrete surface by a forklift exerting a constant 1000 N force. The frictional force between the crate and the concrete is a constant 600 N.

The crate is initially stationary and is pushed for a distance of 10 m.

 

  1. What is the kinetic energy of the crate after the push?
  2. At what speed is the crate moving after the push?
Expert Solution
Step 1

Mass of crate (m) = 100 kg Applied horizontal force (F) = 1000 NFrictional force between crate and the concrete surface = 600 NInitial speed of crate (u) = 0msDistance moved by the crate (d) = 10 m
