Answer:
The magnitude of the force of friction equals the magnitude of my push
Explanation:
Since the crate moves at a constant speed, there is no net acceleration and thus, my push is balanced by the frictional force on the crate. So, the magnitude of the force of friction equals the magnitude of my push.
Let F = push and f = frictional force and f' = net force
F - f = f' since the crate moves at constant speed, acceleration is zero and thus f' = ma = m (0) = 0
So, F - f = 0
Thus, F = f
So, the magnitude of the force of friction equals the magnitude of my push.

The centripetal acceleration of the car is related to its speed by the relationship
where ac is the centripetal acceleration, v is the car's speed and r is the radius of the circular orbit.
Looking at the formula, we can see that if we triple the speed (v'=3v), the centripetal acceleration becomes
so, the centripetal acceleration increases by a factor 9.
