Question

a constant force of 25 newton is applied on a stationary body of mass 2 kg acceleration of a body is 12.5 metre per second square what is the speed of the body after 4 seconds​

Answer 1

Explanation:

we know Force(f)= mass(m) × velocity (u) . so according to the question here,. 25=2×u . then, u= 12.5m/s. so initial(u) velocity = 12.5 m/s . time = 4s and a = 12.5m/s^2

we know a=(v-u)/t .

so , 12.5 = (v-12.5)/4

so, v-12.5=12.5×4=50

so v= 50+12.5=62.5m/s
