Answer to Question #96988 in Mechanics | Relativity for Jacqueline Sakala

Question

A 5kg object which is initially at rest is acted upon by a 25N net external force. What is the speed of the object after 4 seconds?

Answer 1

$$a=\frac{F}{m}=\frac{25}{5}=5\frac{m}{s^2}$$

$$v=at=(5)(4)=20\frac{m}{s}$$
