Answer:

Step-by-step explanation:

Newton's second law states that the applied force is directly proportional to the rate of change of momentum

momentum = mass x velocity

Rate of change in momentum = (final momentum - initial momentum)/time

Rate of change in momentum = m(v - u)/t

where

v is final velocity

u is initial velocity

t is times

Recall,

Acceleration = (v - u)/t

Thus, the equation becomes

Force = ma

This means that as the force increases, the acceleration increases.

Considering the given scenarios,

First piano is pushed by force from the man

For second piano, there is additional force from the woman and the mass of the piano remains the same. Since there is more force, there is more acceleration. Thus,

Acceleration is greater in B
