Thats what i thought Janus It seemed to me that there was information missing but since my class is a computer class the computer wouldn't accept an explanation such as that but this is what the computer said i was supposed to do after i got it wrong. The correct answer is: 6.47 m. The...

ok i will work on it thanks for the help

ok but how would i do that for the moon all i have its mass but i need a force or acceleration and since i want excel how would i derive a force?

i don't really have any equations that deal with this problem except Force of gravit=Gm1m2/r2 i don't know how to do it

Need Help! Gravitational Problem I am kinda lost here was hoping someone could help me out here thanks a ton The year is 2115. There is a high jump competition on planet Mars. An athlete of mass 72 kg who has been clearing a height of 2.44 m on Earth just the week before is competing here...

thanks for the help i was working on that problem forever and wasnt sure how to handle it i appreciate it. thanks

i don't even know how to derive an equation for this problem i am confused if someone would just show me how to derive the equation that would be appreciated not looking for an answer just how to do it. A roller coaster is designed so that after a large drop, the cars enter a circular path...

thanks for the help i used that equation but for some reason the computer didnt like it the course tells me to use the significant figure rule then doesn't use it later so the accepted answer was 1.872s-1 but thanks for the help again i really appreciate it.

i used the equation W=√g/µr but it was incorrect

One of the amusements at many carnivals is a rotating cylinder. The customers step inside and stand with their backs to the wall. The cylinder spins very rapidly, and at some angular velocity the floor is pulled away. The thrill-seekers now hang like flies on the wall. If the radius of the...
