On a body weighing 200 g, a force of 0.1 N acts for 5 seconds. what speed will the body acquire during this time?

Given:

m = 200 grams = 0.2 kilograms – body weight;

F = 0.1 Newton – the force acting on the body;

t = 5 seconds – the period of time during which the force acted on the body.

It is required to determine v (m / s) – the speed that the body will acquire as a result of the action of the force.

Since the condition of the problem is not specified, we assume that the body was at rest before the start of the action of the force. Then, the acceleration that the force imparts to the body is equal to:

a = F / m = 0.1 / 0.2 = 0.5 m / s ^ 2.

Then the speed will be equal to:

v = a * t = 0.5 * 5 = 2.5 m / s.

Answer: in 5 seconds, the body will acquire a speed equal to 2.5 m / s.
