A triangular crate is slided along the inclined face of the tower as shown in the figure. The crate starts with a initial velocity of 10 m/s and slides till B on the inclined surface and it traces a parabolic path to strike the ground at C. If the crate is of 4 kg mass and the height of the tower is 30 m, find the horizontal distance the crate travel's to strike the ground from the starting of its travel. 1) 31.9 m 

Taking the point A
as the datum : The horizontal equation
of motion from B to C : Substuting in for
x we have : So the total horizontal distance travelled from point A to point C is 31.9 m
