Question

A box moves 5m horizontally when force F=10N is applied at an angle 0=30°.

Answer 1

Answer:

43.3J

Explanation:

Given parameters:

Force  = 10N

Distance  = 5m

Angle  = 30°

Unknown:

Work done  = ?

Solution:

Work done is the force applied to move a body through a particular distance;

 Work done  = Force x distance cos Ф

Now insert the parameters and solve;

     Work done  = 10  x 5 cos 30 = 43.3J
