Question

question 5
what is the force required to stop a 4 kg object accelerating at 4 m/s²? see slides 9-8-25
f = ma

○ 1 n
○ 2 n
○ 16 n
○ 4 n

Explanation:

Step1: Identify values for m and a

Given mass \( m = 4 \, \text{kg} \), acceleration \( a = 4 \, \text{m/s}^2 \).

Step2: Apply formula \( F = ma \)

Substitute values: \( F = 4 \times 4 \).
Calculate: \( F = 16 \, \text{N} \).

Answer:

16 N (corresponding to the option "16 N")
