Question

X=t^3+3t^2+2t thenfind the velocity at time of 3 seconds

Answer 1

Answer:

hey mate here is ur ans

Explanation:

x = t³+3t²+2t

velocity is the rate of change of distance

dx/dt = 3t²+6t+2

at t = 3

so dx/dt = v = 3(3)²+6(3)+2 = 27+18+2 = 47 m/s

hope it help u

Answer 2

Answer:

Explanation:

Differentiating displacement with time gives velocity so answer is 47 m per sec
