To find the time a body needs to attain a certain velocity, we can use the equation v = u + at, where v is the final velocity, u is the initial velocity (in this case, 0m/s), a is the acceleration, and t is the time. We can rearrange this equation to solve for t: t = (v-u)/a.

In this scenario, the body has a mass of 60kg and is acted on by a constant force of 80 Newtons. Using Newton's second law of motion, F = ma, we can calculate the acceleration of the body as a = F/m = 80N/60kg = 1.33m/s^2.

Plugging in the values, we get t = (50m/s - 0m/s)/1.33m/s^2 = 37.59 seconds. Therefore, it will take the body approximately 37.59 seconds to attain a velocity of 50m/s from rest under the given conditions.
