Answer:
Velocity
Explanation:
Velocity is an object's change in motion per unit time in a specified direction
The crate would slide forward
Answer:
Explanation:
The equivalent of Newton's second law for rotational motions is:
where
is the net torque applied to the object
I is the moment of inertia
is the angular acceleration
In this problem we have:
(net torque, with a negative sign since it is a friction torque, so it acts in the opposite direction as the motion)
is the moment of inertia
Solving for , we find the angular acceleration:
Because of the axis of the earth. It takes 24 hours to rotate 360 degrees.
