According to galelio., he told that a person who is at rest, will remain at rest and a person in motion will remain in motion until some external force is applied. But if a person lying at rest on his bed wants to get up, he can easily do that and he walks off even though no extra external force was applied. How was he able to do so?
a body is moving with a velocity of 15m/s and it comes to rest in 20m/s, what was the acceleration
