Question

You push on a crate that sits on a smooth floor, and it accelerates. If you apply four times the net
force, how much greater will be the acceleration? Show your answers mathematically and justify
your answers.

Answer 1

Frictional force is zero $F_{fr}=0$

According to the second Newton's law $F_{net}=ma_0$ . So, we have

$4F_{net}=ma=m\cdot4a_0$ .

Acceleration will increase to 4 times.
