Question

1]The angular speed of a motor wheel is increased from 600 rpm to 1200 rpm in 4 seconds.Calculate how many revolutions does the engine make during this time.

2]The angular velocity of flywheel changes from 240 rpm to 120 rpm in 6 seconds.
Calculate the no. of revolutions it will make before coming the rest.

Answer 1

n = 300 revolution

Explanation:

Given that,

Initial speed of the wheel,

Final speed of the wheel,

(1) The rate of change of angular velocity per unit time is called the angular acceleration of the wheel. It is given by :

(2) Let is the angular displacement. It can be calculated using second equation of motion as :

(3) Let there are n number of revolutions it make in this period of time. It is given by :

n = 299.94

or

n = 300 revolution
