Answer to Question #205544 in Physics for Morgan Hopkin

Question

Matthew and Dylan want to hand in a late assignment to Miss Takken but because she is angry they don’t want to approach her. So they put a plank up to the science room window (height 6 m vertically) and slide the 1.3 kg assignment up to Miss Takken. If the slide will lose 15 % due to friction, with what initial speed must they slide the assignment to just reach Miss Takken’s hand with zero velocity?
