A cyclist is riding with a speed of 27km/h .As he approaches a circular turn on the road of radius 80m, he applies brakes and reduces his speed at the constant rate of ,5m/s every second. What is the magnitude and direction of the net acceleration of the cyclist on the circular turn?
b. Two inclined planes frictionless tracks ,one gradual and the other steep meet at A from where two stones allowed to slide down from rest .one on each track. Will the stones reach the bottomat the same time?Will they reach there with the same speed? show mathematically.
