Tonya was injured roller skatig. while she was skating she fell and twisted her knee. this tore the connecting her lower leg to her upper leg. do you think she will still be able to walk?

It would depend on how bad the tear is. You have tendons in your knee, most notably acl and pcl and if you tear those bad enough, you will not be able to walk

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )
