A fullback preparing to carry the football starts from rest and accelerates straight ahead. He is handed the ball just before he reaches the line of scrimmage. Assume that the fullback accelerates uniformly (even during the handoff), reaching the line with a velocity of 8.04 m/s. If he takes 1.17 s to reach the line, how far behind it did he start?

A fullback preparing to carry the football starts from rest and accelerates straight ahead. He is handed the ball just before he reaches the line of scrimmage. Assume that the fullback accelerates uniformly (even during the handoff), reaching the line with a velocity of 7.56 m/s. If he takes 1.04 s to reach the line, how far behind it did he start?
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle travel from start to stop?

PRINTER VERSION < BACK NEXT Chapter 02, Problem 88 A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 2.53 s. Then, during a negligible amount of time, he changes the magnitude of his acceleration to a value of 1.00 m/s. With this acceleration, he continues in the same direction for another 1.13 s, until he reaches a speed of 7.55 m/s. What is the value of his acceleration (assumed...

A three-wheeled car moving along a straight section of road starts from rest, accelerating at 2.00 m/s² until it reaches a speed of 26.0 m/s. Then the vehicle moves for 77.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the three-wheeled car in motion (in s)? (b) What is the average velocity of the three-wheeled car for the motion described? (Enter the magnitude...
