An object B is projected upwards from a height of 60m above the ground with a velocity of 20ms-1 at 30° to the horizontal. At the same time, an object Q is projected from the ground
upwards towards B at 30° to the horizontal. If B and Q collide, at a height of 60m above the
ground while they are both moving downwards,
1) Find the speed of projection of Q
2) The kinetic energy of B just before colliding with Q if it's mass is 1/2kg.
3) The horizontal distance between the points of projection.
