A force acts on a body of mass 15g and causes the body to move with acceleration of 40.0ms2.calculate the force acting on the body.

The given mass is $15 \text{ g}$.

$$m = 15 \text{ g} \times \frac{1 \text{ kg}}{1000 \text{ g}} = 0.015 \text{ kg}$$

The acceleration is $40.0 \text{ ms}^{-2}$.

$$a = 40.0 \text{ ms}^{-2}$$

The formula for force is $F = ma$.

$$F = (0.015 \text{ kg}) \times (40.0 \text{ ms}^{-2})$$ $$F = 0.6 \text{ N}$$

The force acting on the body is $\text{0.6 N}$.
