What force would be needed to produce an acceleration of $4 \, m s^{-2}$ on a ball of mass $6 \, kg$?

(D) According to Newton's second law of motion,the force $(F)$ is the product of mass $(m)$ and acceleration $(a)$.
Formula: $F = m \times a$
Given:
Mass $(m) = 6 \, kg$
Acceleration $(a) = 4 \, m s^{-2}$
Calculation:
$F = 6 \, kg \times 4 \, m s^{-2} = 24 \, N$
Therefore,the force required is $24 \, N$.
