Question
A rocket starts from rest and accelerates to a speed of 200 meters per second in 40 seconds. What is its acceleration?
Solution
The acceleration of an object can be calculated using the formula:
Acceleration = Change in Velocity / Time Taken
In this case, the rocket starts from rest, so its initial velocity is 0. Its final velocity is 200 meters per second, and the time taken to reach this speed is 40 seconds.
So, the acceleration of the rocket is:
Acceleration = (200 m/s - 0 m/s) / 40 s = 5 m/s²
So, the rocket's acceleration is 5 meters per second squared.
