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 ?

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

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
