Let's first calculate the acceleration of the motorbike.
00:06
So the acceleration, the average acceleration, is the change in velocity over the change in time, v minus u over t.
00:15
And the speed we know goes from rest to 60 miles an hour.
00:22
And this happens in a time of four seconds.
00:29
So let's convert this time of four seconds to hours.
00:34
So we know there are 3 ,600 seconds every hour.
00:43
And hence we get an acceleration of 5 .4 times 10 to the 4 miles per square hour.
00:58
Now that we have the acceleration, we can calculate the time it takes to reach the maximum speed.
01:17
So the time it takes to reach maximum speed, we can just manipulate the equation above.
01:23
And rearrange it.
01:25
So t is equal to v minus u over a, the constant acceleration.
01:34
And we know the maximum speed is 1803 .58 ,000 miles per hour.
01:43
The initial speed is zero.
01:45
The acceleration we calculated as 5 .4 times 10 to the 4...
