(A) A flywheel 1.2 m in diameter accelerates uniformly
from rest to 2000 rev/min in 20 s. What is the angular
acceleration?
[12 marks]
(B) A car of mass 1450 kg travels along a flat curved road
of radius 450 m at a constant speed of 50 km/hr. Assuming that the
road is not banked, what force must the tyres exert on the road to
maintain motion along the curve?
