Question

the momentum p of a body is varying with time t as p=3t3+ 2t2 +1.force acting on the particle at t = 1sec is. ​

Answer 1

Answer:

13 N

Explanation:

$F=dp/dt\\ =d(3t^{3}+2t^{2}+1)/dt\\ =9t^{2} +4t$

∴Force at time t=1 sec

                  F=9(1)²+4(1)

                    =9+4

                    =13 N
