Kinematics Question 356

Question: Stopping distance of a moving vehicle it’s directly proportional to

Options:

A) square of the initial velocity

B) square of the initial acceleration

C) the initial velocity

D) the initial acceleration

Show Answer

Answer:

Correct Answer: A

Solution:

Let s be the distance travelled by the vehicle before it stops. Final velocity v=0 , initial velocity = u Using equation of motion v2u2= 2aS

02u2= 2aS Stopping distance, =u22a
