Answer:
Position at t= 4 seconds is 144 m
Explanation:
It is given that acceleration, a = 18 t, where t is the time.
We know that Velocity,
Substituting value of a,
Velocity,
We know that at t = 0, v = -12 m/s
So,
So velocity,
We also know that displacement,
Substituting value of v,
Displacement,
We know that at t = 0, particle is at origin, x =0.
So,
Displacement,
At t = 4 seconds
Position at t= 4 seconds is 144 m
Work = force x distance
