Question1
An object of mass 1.2 kg is released from rest at the top of a 5 metre plank inclined at 40 degrees to horizontal. Find out the normal reaction of the plane on the object and calculate the time taken for the object to reach the bottom of the plank and also its velocity at that time, (suppose that there are no frictional forces acting).
Question2
A new planet has an average radius 11.4 times that of the earth and a mass 311 times that of the earth. Determine the new planets mass density to earth mass density.
