Question

A rocket achieves a lift-off velocity of 500.0 m/s from rest in 30.0 seconds. Calculate the average acceleration of the rocket.

Answer 1

The average acceleration is 16.6 m/s² ⇒ 1st answer

Step-by-step explanation:

A rocket achieves a lift-off velocity of 500.0 m/s from rest in

30.0 seconds

The given is:

→ The initial velocity = 0

→ The final velocity = 500 meters per seconds

→ The time is 30 seconds

Acceleration is the rate of change of velocity of the rocket

→
`a=(v-u)/(t)`

where a is the acceleration, v is the final velocity, u is the initial velocity

and t is the time

→ u = 0 , v = 500 m/s , t = 30 s

Substitute these values in the rule

→
`a=(500-0)/(30)=(500)/(30)=16.6` m/s²

The average acceleration is 16.6 m/s²
