Question
Could I get question 4 part C answered?
You are swinging a tennis racquet (omega = 10 rad, alpha = rad/s^2). The point A is near the tip of the racquet (r=0.7m), and B is near the grip (r = 0.1 in) Calculate the instantaneous tangential acceleration of points A and B Calculate the instantaneous radial acceleration of points A and B Two cars are turning a sharp corner at the same linear velocity (v = 30m s). Car A is in the inner lane (r = 60m), and car B is in the outer lane (r = 70m). Calculate the angular velocity (omega) of the cars A and B. Calculate the instantaneous radial acceleration of the cars A and B. If it starts to rain and the road gels slippery, explain which car would likely to slip out first, and how the driver can prevent slipping from happening. Make sure to include terms radial acceleration and centripetal force in your answer.Explanation / Answer
4 C) radial acceleration of car A, a_radA = v^2/rA
= 30^2/60
= 15 m/s^2
radial acceleration of car B, a_radB = v^2/rB
= 30^2/70
= 12.86 m/s^2
car A has more radial acceleration than car B.
so, car A would likely to slip out first.
To avoid slipping the driver has to reduce the speed of the car or he has to take the turn in the outer lane.
