Question

Physics

Proposition.

You and your friends are learning to play hockey, and you decideto use physics to get better by analyzing your movements. You areskating directly towards your friend at (5.98, 0) M/S who is alsoskating directly towards you to get the puck at a constant velocityof (-2.7, 0) M/S, and both of you reach the puck at the same time,so you collide and stick together. At the same time your hockeyhelmet with a mass of 5 kg goes flying away with a velocity of (0,2.68) m/s. You have a mass of 74 Kg, your friend has a mass of 68kg.

The questions:

1) In vector form, what is you and your friends velocityafter you collide?

2) after the collision the puck is not moving on the iceand another player hits the puck towards the goal. If the averagehockey player can apply a force of 80N over a 0.1s time and thegoal is 15m away then provide evidence of whether or not the puckwill reach the goal. the frictional force a puck experiences is 10Nand the mass of a puck is .25kg. Consider friction in this casesince the puck is made of a rough material.

Please show all work and explain why you are using the equationsyou are using !! Thank you so much. My physics teacher doesn'tteach at all.
