Question

How much force would you need to accelerate a 4 kg object from a standstill to 5 m/s2?

Answer 1

To solve this, we use Newtons 2nd law of motion which states that F = m⋅a . This means that a force F is required to make a body of mass m accelerate with an acceleration of a . So if a body of 4kg is to be accelerated by a force 17N then its acceleration can be found by putting into the formula F = m⋅a .
