A) \[2\text{ }m/s\]
B) \[\sqrt{2}\text{ }m/s\]
C) \[1\text{ }m/s\]
D) \[0.2\text{ }m/s\]
Correct Answer: A
Solution :
Kinetic energy is the energy possessed by a body due to its velocity (v) given by \[K=\frac{1}{2}m{{v}^{2}}\] ...(i) Momentum (p) = mass (m) x velocity (v)... (ii) Given, \[K=P\] \[\therefore \] \[\frac{1}{2}m{{v}^{2}}=mv\] \[\Rightarrow \] \[v=2m/s\]You need to login to perform this action.
