A force of is applied on a body of mass resting on a horizontal plane. The body gains kinetic energy of after it moves a distance of . The frictional force is
Step 1: Given data
Force,
Mass of body,
Kinetic energy,
Distance,
Step 2: Find velocity
Step 3: Find acceleration
By Equation of motion
Step 4: Find frictional force
Hence, option B is correct.
