A rocket for a space shuttle is producing a constant acceleration of 2.15 m/s2. What is its velocity 94.0 seconds after the rocket begins to fire?

Answer: 202.1 m/s

Explanation:

Given that,

acceleration of rocket (A) = 2.15 m/s2 velocity (V) = ?

Time taken (T) = 94.0 seconds

Since acceleration is the rate of change of velocity per unit time

i. e Acc = velocity / time

Velocity = Acceleration x time

V = (2.15 m/s2 x 94.0 seconds)

V = 202.1 m/s

Thus, the velocity is 202.1 m/s
