Questions
A solid sphere of mass 2 kg rolls on smooth horizontal surface at . It then rolls up a smooth inclined plane of inclination 30°. Height attained by sphere before stopping
detailed solution
Correct option is D
total kinetic energy of a rolling body is 12mv21+k2r2 when it reaches the maximum height its all energy gets converted into potential energy then 12mv21+k2r2 =mgh v221+25=gh h=v22g75=10020×75=7mTalk to our academic expert!
