An object of mass 16 kg is moving with an acceleration of $3 m / s^{2}$ . Calculate the applied force. If the same force is applied on an object of mass 24 kg, how much will be the acceleration?

Open in App

Solution

Using newton's second law of motion,
$F = m a$
(0.5 Marks)
$F = 16 \times 3 = 48 N$
(0.5 Marks)

For new object,
$F = m_{2} a_{2}$
(0.5 Marks)
$48 = 24 a$
$a = 2 m / s^{2}$
