A constant force acts on a body weighing 200 g, imparting a speed of 1 m / s to it for 5 seconds.

A constant force acts on a body weighing 200 g, imparting a speed of 1 m / s to it for 5 seconds. Determine the force acting on the body.

Given:

m = 200 grams = 0.2 kilograms – body weight;

v = 1 m / s is the speed imparted to the body during the time t;

t = 5 seconds.

It is required to find the force F (Newton) acting on the body.

Let’s find the acceleration:

a = v / t = 1/5 = 0.2 m / s ^ 2.

F = m * a = 0.2 * 0.2 = 0.04 N.

Answer: the force F is 0.04 Newton.
