A) \[\text{100}\,\text{J}\]
B) \[\text{50}\,\text{J}\]
C) \[\text{1000}\,\text{J}\]
D) \[\text{200}\,\text{J}\]
Correct Answer: B
Solution :
Kinetic energy \[=\frac{{{p}^{2}}}{2m}\] (p = momentum, m = mass) \[=\frac{10\times 10}{2\times 1}\] \[\text{=50}\,\text{J}\]You need to login to perform this action.
