Answer:
The force needed to stop them in the same time is 4mV/dt
Explanation:
We know that momentum o is equal to mass x velocity
Therefore, for one ball the momentum will be o1= 2m x 2v = 4mv
for another ball the momentum will be o2=4m x 4v = 16mv
Newton's second law says force is thr rate of change of momentum.
According tot he problem we need to stop both the masses hence the final momenta is zero.
F = dp/dt = 4mV/dt
