A car with 58-cm-diameter tires accelerates uniformly from rest to 20 m/s in 10 s. How many times does each tire rotate?

Solution Here we have to calculate the no of rotations of car tire in 10 seconds.to calculate that first we have note down the given data Given data: Initial speed of car v = 0 i Final speed of the car v = 20 m/s Time taken to increase speed is t = 10 s Radius of the car tire r = d/2 = 58 cm/2 = 0.29 m Initial angular speed of car is =0 rad/s The angular acceleration of car obtained by expression v = v0+at a = vv /t 0 a = v/t v0= 0 m/s The distance travelled by the car during the time it is accelerating calculated by the relation 2 2...
