Physics-Kinetic Energy
NEET Physics Kinetic Energy MCQ Question
Type: MCQ-numerical-Medium-Class 11
A car of mass 1000 kg is moving with a velocity of 18 km/h. Calculate the kinetic energy of the car and choose the correct option.
A
25 x 10^4 J
B
50 x 10^4 J
C
50 x 10^4 J
D
25 x 10^4 J
Correct Answer
Option A
Detailed Explanation
The velocity of the car is converted to 5 m/s (since 18 km/h = 5 m/s). The kinetic energy is given by K = 1/2 mv^2 = 1/2 * 1000 kg * (5 m/s)^2 = 1.25 x 10^4 J.
