Explanation:
Question 1:
Given:
Initial velocity,
Final velocity,
Time,
Acceleration,
Now, displacement of the tire is given as:
Displacement of tire in 1 revolution is equal to its circumference.
Therefore, displacement in 1 revolution =
Now, number of revolutions is given as:
Therefore, the number of revolutions are 57.
Question 2:
Given:
Radius of the wheel is,
Angle of rotation is, °
Converting degree to radians, we get:
Now, path length is given as:
Therefore, the path length of a point on the wheel is 4.52 m
Question 3:
Radius of the wheel is,
Angle of rotation is, radians
Now, path length is given as:
Therefore, the path length of a point on the wheel is 1531.2 m.
