# A crate of mass \(m\) is pulled from rest across a frictionless horizontal floor by a constant net horizontal force. The crate reaches a final speed \(v\) at time \(t = T\). What is the ratio of the average power delivered by the net force over the time interval from \(t = 0\) to \(t = T\) to the instantaneous power delivered by the net force at time \(t = T\)?

A crate of mass \(m\) is pulled from rest across a frictionless horizontal floor by a constant net horizontal force. The crate reaches a final speed \(v\) at time \(t = T\). What is the ratio of the average power delivered by the net force over the time interval from \(t = 0\) to \(t = T\) to the instantaneous power delivered by the net force at time \(t = T\)?

- **A.** \(\dfrac{1}{4}\)
- **B.** \(\dfrac{1}{3}\)
- **C.** \(\dfrac{1}{2}\)
- **D.** \(1\)
