A constant force of 6N was applied to a stationary body weighing 20 kg. What speed will it get in 15s?
| December 2, 2020 | education
The body is motionless – v0 = 0m / s
you can find the acceleration of the body: F = ma
a = F / m = 6H / 20kg = 0.3m / s2
a = v-v0 / t = v / t
v = at = 0.3m / s2 * 15s = 4.5m / s
Answer: 4.5m / s
