Question

A car is traveling south at 8.77 m/s. It then begins a uniform acceleration until it reaches a velocity of 47.8 m/s over a period of 3.84s. What is the car's acceleration?

Please help !

Answer 1

The acceleration of the car is 10.16m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 8.77m/s

Final velocity = 47.8m/s

Time duration = 3.84s

Unknown:

Acceleration of the car = ?

Solution:

To find the acceleration, we must bear in mind that this physical quantity is the change in velocity with time;

Acceleration =
`(V - U)/(T)`

V is the final velocity

U is the initial velocity

T is the time taken

Input the parameters and solve for acceleration;

Acceleration =
`(47.8 - 8.77)/(3.84)` = 10.16m/s²

The acceleration of the car is 10.16m/s²
