Question

# A body of mass $$m_{1}$$ projected vertically upwards with an initial velocity u reaches a maximum height h. Another body of mass $$m_{2}$$ is projected along an inclined plane making an angle $$30^{{0}}$$ with the horizontal and with speed u. The maximum distance travelled along the incline is

A
2h
B
h
C
h2
D
h4

Solution

## The correct option is C 2hWhen thrown vertical, $$v^2-u^2=2gh;v=0$$On inclined plane, $$v^2-u^2=2gsin\theta h_1=gh_1\ as\ \theta=30^o$$From above equations, $$h_1=2h$$Physics
