A rocket launching in the Ukraine accelerates upwards from rest to a speed of 12 km/s in 8
seconds. Calculate the acceleration

1.5 km/s²

Explanation:

Given that,

Initial speed Vi = 0 km/s

Final speed Vf = 12km/s

Acceleration A = ?

Time taken T = 8 seconds

Recall that acceleration is the rate of change of velocity per unit time

i.e acceleration = (Vf - Vi)/T

A = (12km/s - 0km/s) / 8 seconds

A = 12km/s / 8 seconds

A = 1.5 km/s²

Thus, the acceleration of the rocket is 1.5 km/s²

Too long
