Question
Motion along a Line with Constant Acceleration. A car is speeding up and has an instantaneous
velocity of 1.0 m/s in the +x-direction when a stopwatch reads 10.0 s. It has a constant
acceleration of 2.0 m/s² in the x-direction. (a) What change in speed occurs between t = 10.0 s and
t= 12.0 s? (b) What is the speed when the stopwatch reads 12.0 s?
