Question 972962
2) An F1 racing car has a top speed of 310 km/hr and a wheel diameter of 675mm. When the car is travelling at its top speed [3 marks]:
a)	What is the linear speed of a point at the edge of the wheel farthest from the ground with respect to the ground? Express your answers in mm/min.
b)	Determine the angular velocity of the wheel in rad/min.
c)	Determine the angular displacement in radians of a point on the wheel in 0.015 min.
***
b)Angular velocity={{{310 (km/hr)*(1000m/km)(2(pi)rad/rev)*(rev/(.675(pi)m))(hr/60min)=(310*1000*2/(.675*60))(rad/min)=15308.64 (rad/min)}}}
..
a)What is the linear speed of a point at the edge of the wheel farthest from the ground with respect to the ground? =twice the speed of the car
{{{620 (km/hr)(1000000mm/km)*(hr/60 min)}}}=620*1000000/60=10.3*10^6 mm/min
..
c)Determine the angular displacement in radians of a point on the wheel in 0.015 min.
.015*15308.64=229.63 radians
