Got it! 4.4 m/s is much more resonable. Thank you.

Homework Statement A 1100kg car is traveling at 24m/s before it hits a 18m patch of mud with a 1.7 x 10^4 net horizontal resistive force. What is the cars speed as it leaves the mud patch? Homework Equations Change in Uint= fd KE= 1/2mv^2 W= Fd The Attempt at a Solution 1/2mv^2 = f(mud on...

I understand now! Thank you all very much! :)

Thanks! I think I found more information. In an example problem, it uses 6.0 x 10^24 kg as Earth's mass. And Moon's as 7.35 x 10^22 kg. Will I use Earth's mass to find the m person? And then use that information to solve F moon on person on Moon's surface = G(m moon x m person)/r^2?

Homework Statement On Earth, an average person's vertical jump is 0.40m. What is it on the Moon? Homework Equations Fg 1 on 2 = G(m1m2/r^2) G= 6.67 x 10^-11 The Attempt at a Solution r= 0.40m F Earth on person on Earth's surface = 6.67x10^-11(m Earth x m person)/(0.40)^2 r=? G moon = ? F moon...
