What is the change in magnitude

Reference no: EM13698518

Problem: A football player has in initial velocity of Vi = -1.31 i + 2.6 j m/s. He gets hit for 3 seconds and experiences an acceleration of 4.7 i + -5.9 j m/s.

Part I: What is the new velocity?

Part II: What is the change in magnitude (speed)?

Part III: What is the change in direction (angle of motion)?

Part IV: What if the hit lasts 2 seconds?

Please give me an explanation for above problem.
