Question

the displacement S of a particle at time t second is given by S=t^2(t-3), then find the velocity of the particle at t=25 second​

Answer 1

Answer:

V = 1725 units/second.

Step-by-step explanation:

S = t^2(t - 3)

S = t^3 - 3t^2

Velocity = derivative of displacement

So V = dS/dt = 3t^2 - 6t

At t = 25, V = 3(25)^2 - 6(25)

= 1725
