Qu 1. Find the time interval between a particle reaching the bottom of a smooth slope of length 5m and inclination 1 in 98, and another particle reaching the bottom of s smooth slope of length 6m and incline 1 in 70. Both particles are released from rest at the top of their respective slopes at the same time.
Qu 2. A mass of 15kg lies on a smooth plane of inclination 1 in 49. One end of a light inextensible string is attached to this mass and the string passes up the line of greatest slope, over a smooth pulley fixed at the top of the plane and has freely suspended a mass of 10kg at its other end.
If the system is releases from rest, find the acceleration of the masses and the distance each travels in the first 2s. Assume that nothing impedes the motion of either mass.
Any attempts are welcome!!
