Answer to Question #141530 in Mechanics | Relativity for Fletcher Madden

Question

A constant force F acts on a truck over a distance s and for a time t. The momentum gained by the truck is?

Answer 1

Explanations & Calculations

• According to the equation $\small F =\large \frac{\Delta mv}t{}$ this question could be solved

$\qquad\qquad \begin{aligned} \small F &= \small \frac{\Delta mv}{t}\\ \small \Delta mv&= \small F\times t\\ \end{aligned}$

• Assuming no friction, the change in the momentum (what is gained by an object over the time) is given by $\small F\times t$ for a constant force.
