Question

The motion of a particle moving in a straight line is given by s = t 3 - 3t 2 + 2t + 5.
After 4 seconds, the velocity and accelerations are​

Answer 1

Answer:

v=26m/s and a=18m/s^2

Explanation:

V=dx/dt

V=3t^2 - 6t+2

V=3(4)^2-6(4)+2

v=48-24+2

v=26m/s

a=dv/dt

a=6t-6

a=6(4)-6

a=24-6

a=18m/s^2

I hope the answer will help you mate
