Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am kind of new to this physics thing, and I need some help. Any advice you can give me is more than welcome. :)

1. An 850 kg (1878 lb) dragster, starting from rest, attains a speed of 27.0 m/s (60.5 mph) in 0.59 s.

A. Assume that the driver has a mass of 68 kg. What horizontal force does the seat exert on the driver?

What formula would I use to find the horizontal force?

11. A 66 kg swimmer steps off a 10.4 m tower. What is the swimmers velocity hitting the water?

What formual would I need to use to find this out?

If you guys can give any help it would be most appreciated. I know this must be really simple to you guys, but I am stuck on it.
