A) impulse
B) change in momentum per unit mass
C) change in KE per unit mass
D) total change in energy
Correct Answer: C
Solution :
Area of acceleration-displacement curve gives change in KE per unit mass. \[\frac{1}{2}=m({{v}^{2}}-{{u}^{2}})=Fs=\frac{mdv}{dt}\times s\] \[\therefore \] \[\frac{\text{Change in KE}}{\text{Mass}}=\frac{dv}{dt}\times s\]
