Near the end of a marathon race, the first two runners are separated by a distance of 75.0 m. The front runner has a velocity of 3.25 m/s, and the second runner has a velocity of 4.75 m/s. What is the magnitude of the velocity of the second runner relative to the first? velocity of the second runner relative to the first: m/s Incorrect If the front runner is 215 m from the finish line, who will win the race, assuming both runners run at constant velocity? Both runners cross the finish line at the same time. front runner second runner By what distance does the winning runner finish ahead of the next runner?

12. Which of the following statements is not valid for a projectile? Take upward direction as positive. a. The y component of the velocity of the projectile is zero at the highest point of the projectile's path. b. The x velocity on a projectile is constant at any point on its path if we ignore air resistance. c. The acceleration of the projectile is positive and decreasing when the projectile is moving upwards. d. The acceleration of the projectile is a constant negative value.

A soccer ball is kicked from the ground with an initial speed of 20.2 m/s at an upward angle of 40.9*. A player 52.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s?. Number i Unit
