A car initially traveling at a speed of 15.0 m/s accelerates uniformly to a speed of 20.0 m/s over a distance of 40.0 meters. What is the magnitude of the car's acceleration? Answers:
1.1 m/s^2
2.0 m/s^2
2.2 m/s^2
9 m/s^2

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
