Question

The displacement of a particle is given by x(t)= 4 t^2 +8 t m. Its velocity at t = 5 s will be:-

Answer 1

Answer:

x(t)= 4 t^2 + 8 t m

 velocity at t =5 s will be:

        formula of velocity = displacement/ time

                                         = d/dt ( 4t^2 + 8t )

                                         = 8t + 8

now , put t = 5 s

                                         = 8(5) +8

                              ANS  = 48 m
