NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
A block of mass 2 kg is initially at rest on a frictionless surface. A constant horizontal force of 10 N is applied to the block. What is the kinetic energy of the block after it has moved 5 meters?
A
25 J
B
50 J
C
75 J
D
100 J
Correct Answer
Option B
Detailed Explanation
Using the work-energy theorem, the work done by the force is equal to the change in kinetic energy. Work done = Force x Displacement = 10 N x 5 m = 50 J. Hence, the kinetic energy of the block after moving 5 meters is 50 J.
