Q. A uniform rope of mass 46 g and length 120 cm hangs from a ceiling. (a) Find the speed of a transverse wave on the rope at 39 cm from the lower end. (b) Find the time a transverse wave takes to travel the length of the rope.

Q. A racing car start from rest in the distance and accelerates with a uniform rate of speed 35m/s in 11 sec moving in a circular path of radius 500 m assuming constant tangential acceleration find (1) the tangential acceleration. (2) The centripetal acceleration when the speed is 30 m/s.
