Answer:
a. s = 0.96 m
b. s = 2.15 m
Explanation:
a.
The relationship between the linear displacement and the angular displacement is given as follows:
where,
s = linear distance covered = ?
r = radius of wheel = (6 in)(0.0254 m/1 in) = 0.1524 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 0.96 m</u>
<u></u>
b.
Assuming, we have to find linear displacement here, as well:
where,
s = linear distance covered = ?
r = radius of wheel = (13.5 in)(0.0254 m/1 in) = 0.3429 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,
<u>s = 2.15 m</u>
Answer:
finish at the same time
Explanation:
Force equals mass times acceleration. Without friction the net force on both will be equal to component of the force of gravity. Therefore the net force will be mass time acceleration due to gravity times the incline of the hill. Since net force equals mass times acceleration. Now we set net force equals mass times acceleration and the mass will cancel out giving both block the same acceleration and therefore they will finish at the same time
