1. Homework Statement
a point mass is projected at an angle of 60° from the horizontal. it collides with the sphere at a maximum height of trajectory with a sphere of radius of 72.5cm such that it is projected off the sphere once again at an angle of 60° from the horizontal.The sphere, due to the collision, is bounced off the floor. The point mass, in its descent, collides with the sphere again, through the same horizontal of the previous point-mass-sphere collision, and is projected at an angle of 30° below the horizontal . if the density of the sphere is 50kg/m3 and uniform mass distribution then the mass of point mass,m and the initial velocity of the point mass is u. find floor(m + u) . Assume all the collisions are elastic, and the sphere is rigid.
mvi = mvfinal
xf = xo + vot + 0.5 a t2
The Attempt at a Solution
couldn't try because i dont know why does the sphere bounces
someone please tell me why does the sphere bounce then i could probably start as in i know it is because the mass hit it but what exactly is the reason?[/B]
