How much work is done when you push a create horizontally with 100 N across a 10 m factory floor?
b) if the force of friction on the crate is a steady 70 N, show that the KE gained by the crate is
Answer:
300 J
Explanation:
The net work gives the kinetic energy gained. The net force will be 100 N-70 N= 30 N
Work is a product of force and distance hence
Net work=30*10=300 J
Therefore, the kinetic energy gained is 300 N. I assume the first part of the question was already answered
The kinetic energy gained by the crate is 300 Joules
- The kinetic energy gained by the crate is converted to workdone on the crate.
- Kinectic energy = Workdone = Force * Distance
- The resultant force acting on the crate = 100N - 70N
- The resultant force acting on the crate = 30N
- Distance covered by the crate = 10m
Calculate the KE gained by the crate.
KE gained = 30 * 10
KE gained = 300 Joules
Hence the kinetic energy gained by the crate is 300 Joules
