I've got a lot of home work to do still and my book has run out of formulas for the questions my Professor so kindly gave us. I'm not the brightest crayon in the box, and I know you arn't here to do my home work for me. so I'm just asking for some formuals, or somewhere to find formuals to find average force when I'm only given two speeds and the amount of contact time between a ball and bat. highest point-given two velocities, its on an angle (a skier jumping a ramp) but it doesn't give any information about the angle, or how long the ramp is etc. kenitic friction on ice for minimun initial speed- a hockey player hit a puck across come ice and it only went half way. Given the initial speed and that it only reaches half way. I'm supposed to figure out the initial speed he should have given the puck to get it to reach the other player. Finially I keep seeing "magnitude of the force" and I cant remember what this means or what its asking me and I'm getting really frusterated !! please try to help me. Thank you!
