HPS211H1 Lecture : Lecture 4

A wheel starts from rest and has an angular acceleration of4.00rad/s^2. It turns through 10.0 complete revolutions.

A) What is its angular velocity after ithascompleted 10.0 revolutions?

B) How much time does it take to complete10.0revolutions?

A car accelerates uniformly from rest and reaches a speed of 19.4m/s in 8.61 s. The diameters of a tire on this car is 58.1 cm

a) Find the number of revolution the tire makes during the car'smotion, assuming that no slipping accurs.
(N= 45.8 revolution)

b) what is the final angular speed of a tire in revolution persecond?
w=????? rev/s
