Question

On a aircraft carrier, a fighter jet goes from rest to a velocity of 250 mph (miles per hour) when it takes off. It does this in 3 seconds. What is it acceleration ?

Answer 1

Answer:

37.25m/s

Explanation:

Acceleration is the change in velocity of an object with respect to time.

Acceleration = velocity/time

Given

Velocity = 250mi/hr

Convert to m/s

1mile = 1609.344m

1hr = 3600s

250mi/hr = 250mi * 1609.344/1 * 3600

250mi/hr = 402366/3600

250mi/hr = 111.76m/s

Time = 3 seconds

Get the acceleration:

Acceleration = 111.76/3

Acceleration = 37.25m/s

Hence the acceleration is 37.25m/s
