Question

A car is traveling at a speed of 35 m/s. In 15 seconds the car decides to increase their speed to 89 m/s. calculate the cars acceleration

Answer 1

3.6m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 35m/s

Time taken = 15s

Final velocity = 89m/s

Unknown:

Acceleration of the car = ?

Solution:

Acceleration is the rate of change of velocity with time;

Mathematically;

Acceleration =
`(v - u)/(t)`

v is the final velocity

u is the initial velocity

t is the time

Insert the parameters and solve;

Acceleration =
`(89 - 35)/(15)` = 3.6m/s²
