Problem no 08
A car is travelling on a flat circular track of radius 200m at 20 m/s, and has a centripetal acceleration, a = 4.5 m/s^2 (a) If mass of the car is 1000kg, what is the force required to provide the acceleration? (b) If the coefficient of static friction (us) is 0.8, what is the maximum speed at which the car can circle the track?
Problem no 09
The turn table of a record player rotates initially at the rate of 33 rev./min and takes 20 s to come to rest. (a) What is the angular acceleration of the turntable, assuming the acceleration is constant? (b) How many rotations does the turntable make before coming to rest? (c) If radius of the turn table is 0.14m, what is the initial linear speed of a bug riding on the rim? (d) What is the magnitude of the tangential acceleration of the bug at time t = o?
