Q. A moving body undergoes uniform acceleration while travelling in a straight line between points X, Y and Z. The distances XY and YZ are both 40m. The time to travel from X to Y is 12s and from Y to Z is 6s.

What is the acceleration of body?

Q. A uniform disk of radius 0.45 m is mounted on a frictionless, horizontal axis. A light cord wrapped around the disk supports a 0.85kg object. When released from the rest point object falls with a downward acceleration of 4.5m/s^2. Find out the mass of the disk?
