Question

Given momentum P of a particle is varying with time t as P = at +b/sqrt t
where a, b are constant and t is
time, then calculate force on particle as a function of time 't'.

Answer 1

Given Momentum P=a+bt 2 .We know force F=

f

=rateofchangeofmomentum.

Given Momentum P=a+bt 2 .We know force F= dtdp =rateofchangeofmomentum.⇒F=2bt

Given Momentum P=a+bt 2 .We know force F= dtdp =rateofchangeofmomentum.⇒F=2btor Force∝time

there is your answer........
