To an immobile body weighing 20 kg, a constant force of 60 N. What path will this body take in 12 seconds.

Given:

m = 20 kilograms – body weight;

F = 60 Newton – force applied to the body;

t = 12 seconds – time span.

It is required to determine S (meter) – which path the body will cover during the time interval t.

Let’s find the acceleration received by the body as a result of the action of the force:

a = F / m = 60/20 = 3 m / s2.

Since, according to the condition of the problem, the body was initially motionless, then the path traversed by the body will be equal to:

S = a * t ^ 2/2 = 3 * 12 ^ 2/2 = 3 * 144/2 = 3 * 72 = 216 meters.

Answer: in 12 seconds, the body will cover a distance of 216 meters.
