Term
A car decelerates from 60 m/s to rest in a distance of 240 m. The deceleration is _______ m/s^{2}. 

Definition
7.5 m/s^{2}. a = (v_{f}v_{i})/t 


Term
A laser pulse is sent from the earth to the moon and is reflected back. The signal takes 2.7 seconds to complete the trip. If light travels at a speed of 3 x 10^{6} m/s, the approximate distance from the earth to the moon is _________. 

Definition
4 x 10^{8} m Distance = velocity x time 


Term
The time it takes for a plane to change its speed from 100 m/s to 500 m/s with a uniform acceleration in a distance of 1,200 m is _______________. 

Definition
4 seconds average velocity = (v_{i} + v_{f})/2 time = distance / average velocity 


Term
In a velocity vs. time graph, the slope measures
