NEET Physics Question - Kinematics

Rankers Physics

Topic: Kinematics

Subtopic: Equations of Motion

When a car is stopped by applying brakes, it stops after travelling a distance of 80 m. If speed of car is halved and same retarding acceleration is applied then it stops after travelling a distance of

20 m

50 m

75 m

100 m

Solution:

Using the stopping distance formula:

$s \propto u^2$

If speed is halved, new stopping distance:

$s_2 = \frac{100}{4} = 25 \text{ m}$

Solution:
