Question

Projectile motion:

Q A particle of mass m is thrown horizontally from point P, as
shown in the figure, with speed 5 m/s It strikes an inclined plane
perpendicularly as shown The inclination of the plane is
30o with the horizontal Then, the height h shown in the
figure is (Take g= 10 m/s2)

(A) 3 75m â€‹(B) 5 0m
(C) 4 75m â€‹ â€‹ (D) 0 417

Dear Student,let the speed at which it hit is vthen vsin30=5v=10 m/sfrom energy conservation 
m*522=mgh+m*102212 5=10h+50h=37 510=3
