If 1,m ,n are the direction cosines of the line of shortest distance between the lines (x-3)/(2) = (y+15)/(-7) = (z-9)/(5) and (x+1)/(2) = (y-1)/(1) = (z-9)/(-3) then :

A ball is dropped on to a horizontal plate from a height h = 9 m above it. If the coefficient of restitution is e=1/2, the total distance travelled before the ball comes to rest is

Body 1 of mass M is dropped from a height of 1 m and body 2 of mass 3 M is dropped from a height of 9 m. Ratio of time taken by bodies 1 and 2 to reach the ground is
