What should be the coefficient of friction between the car and the road, so that car dose not slip? a. 0.2 b. 0.4 c. 0.6 d. 0.8 2. If a body is moving in a circle of radius ‘r’ with a constant speed ‘v’. Its angular velocity is ... 3. A ball of mass 0.25 kg attached to the end of a string of length 1.96 m moving in horizontal circle. The string will break when tension is more than 25 N. what is the maximum speed with which ball can be move? a. 14 m/s b. 3m/s c. 3.92m/s d. 5m/s
