Question

An object of mass 50 kg is accelerated uniformly from a velocity of 2m/s to 4m/s in
6 s. Find the magnitude of force exerted on the objec

Answer 1

Answer:

16.67 Newton (Approximately)

Explanation:

Initial velocity = u = 2 m/s, Final velocity = v = 4 m/s

Change in velocity = v-u = (4-2)m/s = 2 m/s and this change occurs in 6 sec = t

Acceleration = Rate of change in velocity

$=\frac{v-u}{t}=\frac{2}{6}=\frac{1}{3}m/s^2$

Force = Mass*Acceleration

$Force = 50*\frac{1}{3}=\frac{50}{3}=16.67Newton$
