Question

What is the acceleration of an object that takes 20 sec to change from a speed of 200 m/s to 300 m/s ?

Answer 1

Given:

• initial velocity, u = 200 m/s

• Final velocity, v = 300 m/s

• Time taken, t = 20 sec

To be calculated:

Calculate the acceleration of given object ?

Formula used:

Acceleration = v - u / t

Solution:

We know that,

Acceleration = v - u / t

☆ Substituting the values in the above formula,we get

Acceleration ⇒ 300 - 200 / 20

⇒ 100/20

⇒ 5 m/s²
