Givens.
• The radius of the wheel is 0.680 m.
,
• The applied force is 5.00 N, and it's a tangential force.
,
• The number of revolutions is 1.20.
We need to find the circumference of the wheel, use the circumference formula.
Where r = 0.680 m and pi = 3.14.
The circumference of the wheel is 4.27 meters.
It's important to notice that the circumference represents 1 revolution, so for 1.20 revolutions we have
This means the total distance covered is 5.12 m. However, the displacement is different because it takes into account only the change of position, so basically, the displacement would be 0.20 revolutions because at 1 revolution we are at the same starting point.
Therefore, the total displacement is 0.854 meters.
However, we need to find the angular displacement, so
Hence, the angular displacement is 1.26 radians.
