A small block of mass 
is moving on as mooth horizontal table surface at initial speed 
. It then moves smoothly onto a sloped big block of mass 
. The big block can also move freely on the table surface. After the small block reaches the height 
on the slope, it slides down. Find the height 
.

Text Solution
Verified by ExpertsThe correct answer is:
D
Let the block of mass 
will move till a height 
.
To find 
, consider at the highest point, mass 
and 
moving with the same velocity. Then, by conservation of momentum,
By conservation of energy,
