Question

Calculate the work done by an applied force of 76.0 N on a crate for the following. (Include the sign of the value in your answer.)

a. The force is exerted horizontally while pushing the crate 5.20 m.
b. The force is exerted at an angle of 41.0

Answer 1

Answer:

a) 400.4Joules

b) 262.69Joules

Explanation:

Work is said to be done if the force applied to an object cause the object to move through a distance

Workdone = Force × Distance

Given

Force = 76N

Distance= 5.2m

Work done = 77 × 5.2

Work done = 400.4Joules

b) If the force is exerted at an angle of 41°

Work done = Fdsin theta

Work done = 77(5.2)sin41

Work done = 400.4sin41

Work done = 262.69Joules
