Question

A steam catapult launches a jet aircraft from the aircraft carrier John C. Stennis, giving it a speed of 195 mi/h in 2.90 s. (a) Find the average acceleration of the plane.

Answer 1

The average acceleration of the plane is 0.0186
`(mi)/(s^(2) )`

Step-by-step explanation:

The acceleration of an object is a magnitude that indicates how the speed of the object changes in a unit of time. That is, acceleration is a magnitude that relates changes in speed with the time it takes to occur.

The average acceleration of an object is calculated using the following expression:

`acceleration=(change of speed)/(time)`

In this case:

• change of speed=
  `195 (mi)/(h) *(1 h)/(60 minutes) *(1 minute)/(60 s) =0.054 (mi)/(s)`
• time= 2.90 s

Replacing:

`acceleration=(0.054 (mi)/(s) )/(2.90 s)`

and solving you get:

acceleration=0.0186
`(mi)/(s^(2) )`

The average acceleration of the plane is 0.0186
`(mi)/(s^(2) )`
