Reference no: EM13508500

An 82-kg running back leaps straight ahead toward the end zone with a speed of 7.0 m/s. A 115-kg linebacker, keeping his feet on the ground, catches the running back and applies a force of 873 N in the opposite direction for 0.71 s before the running back's feet touch the ground.

(a) What is the impulse that the linebacker imparts to the running back?

magnitude

direction

(b) What change in the running back's momentum does the impulse produce?

magnitude

direction

magnitude

direction

(d) If the linebacker keeps applying the same force after the running back's feet have touched the ground, is this still the only force acting to change the running back's momentum?

Yes
