Question

An object of mass 50 kg is accelerated uniformly from a velocity of 2m/s to 4 m/s in 1 seconds. Calculate the initial and final momentum of the object

Answer 1

Explanation:

The mass of the object, m = 50 kg

The initial speed of the object, u = 4 m/s

Final speed of the object, v = 8 m/s

1. Initial momentum of the object is given by :

2. Final momentum of the object is given by :

3. The force exerted on the object is given by :

F = 25 N

Hence, this is the required solution

Answer 2

Explanation:

The mass of the object,m=50kg

The
