An 84 kg hockey player skating at 10 m/s to the right collides with another 64 kg player who is standing still. If both players get tangled together during the collision, what is their combined speed?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

If you let go of the notebook after lifting it, will it move? how?

Plz suppose you increase your walking speed from 6 m/s to 13 m/s in a peroid of 3 s. what is your acceleration you in advance.
