Question

At highway speeds, a particular automobile is capable of an acceleration of about 1.6 m/s. At

this rate, how long does it take to accelerate from 36 m/s to 50 m/s? (8.8 s)
Proof please

Answer 1

8.8s

Step-by-step explanation:

Given parameters:

Acceleration = 1.6m/s²

Initial velocity = 36m/s

Final velocity = 50m/s

Unknown:

Time taken for the acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time;

Acceleration =
`(Final velocity - initial velocity )/(time taken )`

Insert the parameters and solve for time taken;

1.6 =
`(50 - 36)/(t)`

1.6t = 14

t = 8.8s
