Solution

The correct options are
B Momentum
C Velocity
D Acceleration
Using Newton's second law, if the mass of the body (m) and the net force (F) acting on it is given, then it's acceleration (a) can be calculated using F=ma.
Once the acceleration of the body is determined, velocity of the body can be calculated using the equations of motion. Once the velocity is known, momentum (p=mv) can be calculated.
