Constant Acceleration in One Dimension ** A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 10.4 m/s and accelerates at the rate of 0.490 m/s2 for 7.00 s. (Define the positive direction to be the direction of motion.) Part 1 What is his final velocity? Part 2 The racer continues at this velocity to the finish line. If he was 309 m from the finish line when he started to accelerate, how much time did he save? Part 3 One other racer was 5.00 m ahead when the winner started to accelerate, but he was unable to accelerate, and traveled at 10.7 m/s until the finish line. How far ahead of him (in seconds) did the winner finish? Access OpenStax College Physics Access OpenStax College Physics for AP@ Courses Submit
