Question

the position of a body is given by a function of time as x = At + 4Bt^3 calculate the instantaneous velocity at t = 5s

Answer 1

Answer:

Explanation:

It is given that, the position of a body is given by :

Where

a and b are constants and t is time

Velocity is given by :

At t = 5 seconds, v = a + 300 b

Acceleration is given by :

a = 24 bt

At t = 5 seconds, acceleration, a = 120b

Hence, this is the required solution.
