Well, 2 actually.
"In stopping from an initial velocity of 35 m/s a motorcycle leaves a streak on the highway. Assuming a deceleration of 20 m/s^2 what was the distance in KM of the streak?"
Okay, so what I (think) I've got here is:
Initial Velocity = 35 m/s
Acceleration = -20 m/s^2
Final Velocity = 0 m/s
What I don't know is how to crunch it properly, and the acceleration being in m/s^2 compounds the problem.
I feel silly asking, but any help would be tremendously appreciated.
