Classical Mechanics Level 1

Momentem associated with an accelerating particle at any time t is given by the function p = 10 t + b \boxed{p = 10 t + b} where b is a constant and p is momentem of particle at time t calculate the force that the particle is experiencing


The answer is 10.

Force=Chenge in momentum /Time

Let pf and pi be final and initial momentum after tf and ti seconds respectively.

Then change in momentum=10tf-10ti=10(tf-ti)

Time =tf-ti

By the formula given in first line, Force=10
