Questions
A cricket ball is hit for a six by the bat at an angle of 450 to the horizontal with kinetic energy K. At the highest point, the kinetic energy of the ball is
detailed solution
Correct option is C
At highest point, speed will remain 12 times (= u cos 450 ).Therefore, kinetic energy will become 1/2 times.Similar Questions
