Question

A car is traveling in a race.The car went from the initial velocity of 35 to the final velocity of 65 in 5 seconds what is the acceleration

Answer 1

Acceleration = 6m/s²

Step-by-step explanation:

Given the following data;

Initial velocity = 35m/s

Final velocity = 65m/s

Time = 5 seconds

To find the acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Mathematically, acceleration is given by the equation;

`Acceleration (a) = (final \; velocity - initial \; velocity)/(time)`

Where,

• a is acceleration measured in
  `ms^(-2)`
• v and u is final and initial velocity respectively, measured in
  `ms^(-1)`
• t is time measured in seconds.

Substituting into the equation, we have

`a = (65 - 35)/(5)`

`a = (30)/(5)`

Acceleration = 6m/s²
