|
|
1500 N
|
|
|
15 N
|
|
|
1.5 N
|
|

Explanation:
Detailed explanation-1: -We can use the formula W = F x d to solve the problem: Work = 10 newtons x 5 meters = 50 newton meters ► 8.1 a.
Detailed explanation-2: -Since the total length of the box 5 metre and force is 15 N, hence, work done will be 5 * 15 = 75 joules.
