Question

force of 5000N is acting on a body of mass 50kg if force of friction on the body is 100N. Calculate how long it takes for the body to gain the velocity of 50m/s from rest​

Answer 1

.5102 s

Step-by-step explanation:

Net force acting to accelerate the body is 5000- 100 = 4900 N

F = ma

4900 N = 50 kg * a then a = 98 m/s^2

v= at

50 m/s = 98 m/s^2 t then t = 50/98 =.5102 s
