Question

(9.2.70) A car drives around a circular track of radius 50 m. The car starts at rest at time t = 0, and its speed increases at a rate of 3.00 m/s. (a) Draw a top view illustrating the motion of the car around the circle, and also a side view showing a free-body diagram for the car (b) Find an equation which gives the magnitude of the net acceleration vector as a function of time (incorporating both radial and tangential acceleration). It's preferable to write the equation in symbolic form, i.e. use symbols instead of numbers. However, any symbol except for time should have a numerical value stated off to the side (c) Given that the coefficient of static friction between the car and the road is 0.60, how much time elapses before the car goes into a skid?
