Work, Energy and Power · Work and kinetic energy
A body of mass 1 kg moves along a straight line with a velocity . The work done on the body during displacement from to 5 m is J.
- (1)0
- (2)250
- (3)1250
- (4)1000
We corrected a printing error in the original paper
Source printed “The work done by the body”; corrected to the intended “The work done on the body” (the key 1250 J is the gain in kinetic energy; the work done by the body would be J).
