A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 12.0 m/s and accelerates at the rate of 0.350 m/s2 for 7.00 s.
The final velocity is 14.45 m/s
The racer continues at this velocity for to the finish line. If he was 300 m from the finish line when he started to accelerate, how much time in s did he save?
3.64 s
One other racer was 5.00 m ahead when the winner started to accelerate but he was unable to accelerate and traveled at 12.4 m/s until the finish line. How far ahead of him in meters did the winner finish?
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
