Question 24.
00:05
In question 24, we are told that a car is traveling of long a road with its engine turning over at an initial velocity of 220 radiance per second.
00:16
The driver then steps on the accelerator for a time of 10 seconds and increases the angular velocity of the engine to 280 radians per second.
00:32
In part a, we're asked, what would be the angular displacement of the engine if the angular velocity remained the same constant as the initial angular velocity of 220 radiance per second? so because i'm assuming constant velocity, i'm going to use the equation that the displacement is the angular velocity times time.
00:56
And because we're assuming the initial value, i'm going to use the initial value that we were given.
01:01
So substituting what i've got, if the engine is turning over a constant angular velocity of 220 radiance per second for 10 seconds, then my angular displacement will be 2 .2 times 10 to the 3 radians.
01:52
In part b, we're asked exactly the same question, but now we're going to assume that our constant angular velocity is the final value, 280 radians per second...
