Question #39583
a) A massless rope is stretched horizontally between two supports that are 3.0 m apart.
When an object of weight 3200 N is hung at the center of the rope, the rope is observed
to sag by 50 cm. Calculate the tension in the rope.
b) b) A ball of mass 5.0X10^-2 Kg starting from rest, falls a height of 4.0 m and then collides
with the ground. The ball bounces up to a height of 2.0 m. The collision with the ground
takes place over a time 4.0X10^-1 S Determine (i) the momentum of the ball immediately
before the collision, (ii) the momentum of the ball immediately after the collision and
(iii) the average force of the ground on the ball.
