Question

a man pushes 10 kg box with 45 n of net force and is moved 4 m. how much work is done? part a what formula is used to solve the problem? formula must start with the vai part b how much work is done?

Explanation:

Part A

Step1: Recall work formula

Work \( W \) is calculated by the formula \( W = F\times d \), where \( F \) is the force and \( d \) is the displacement.

Part B

Step1: Substitute values into formula

Given \( F = 45\ N \) and \( d=4\ m \), substitute into \( W = F\times d \).
\( W=45\times4 \)

Step2: Calculate the result

\( 45\times4 = 180\ J \)

Answer:

Part A: \( W = F\times d \)
Part B: \( 180\ J \)
