Two smooth spheres of equal radii and with masses 2m, 5m are on a horizontal table. the sphere of mass 2m, travelling with speed 3u, collides directly with the sphere of mass 5m, which is traveling with speed u in the same direction. the coefficient of elasticity between the spheres is e 1/4 (i) (5 points) find the speed and direction of each ball after the collision. ii) (5 points) find an expression, involving m and u, for the kinetic energy lost in the collision. (b) (10 points) examine whether or not the following system of forces is in equilib- rium + 5k acting at (-7,5,-5) f2 = 21-j-k acting at(-2,4,-19) fa ij-6ok acting at (-1,2,-2)
