Question

A force of 10N acts on a body of mass 2kg. If the body was initially at rest, calculate the velocity acquired by it in 5s. [Answer: 25m/s]​


if someone give me right answer I give them mark as brainlist

Answer 1

Explanation:

use this equation

Vx = V0 + at

since body is at rest initially, V0 = 0

F = ma

a = F/m = 10/2 = 5m/sec^2

Vx = a*t = 5m/sec^2 * 5sec = 25m/sec
