Dave is entered in a bike race and is waiting stationary at the start line. The gun goes off and Dave speeds up 15 m/s within 5 seconds to take the lead position! Dave pedals at a constant speed for 10 seconds but then slows down for a big turn in the course. He slows from 15m/s to 10m/s in 1 second to take the turn. If Dave sped up from Om/s to 15m/s in 5 seconds, what was his rate of acceleration? What was his acceleration when traveling at 15m/s for 10 seconds? What was his acceleration when slowing from 15m/s down to 10m/s in 1 second prior to making his turn?
