Homework Statement
An object with a mass of 4.0 kg travels with a constant velocity of 4.8 m/s northward. It is then acted on by a force of 6.5 N in the direction of motion and a force of 9.5 N to the south, both of which continue even after the mass comes momentarily to rest.

ok obvisouly im doing something wrong here, does anyone have a list of formulas for projectile motion. I dont seem to have any in the text book, and mastering physics is just giving me questions, no formulas.

ya i did read that, i just needed someone to explain it in away that makes sense to me. I went to my lab today and i am obviously strugglin with this subject so im going to a study group that meets every week. I really do appreciate your guy's help, i just am not the kind of person to figure out...
see the thing that got me was the time fall starts, i didnt know if i plugged in the time threw the window or solved for it. Because i was also looking for height
AVG Speed = 1.35/.210 = 6.43 m/s
a = (vm - vt)/t
9.81 = (6.43 - vt)/(0.105)
vt = 5.40 m/s
5.402 = 0 2 + 2(9.81)d
d = 1.49 m
Object was released 1.49 m above window.
is this correct?
ok heres what im trying to think of in my head. Basically the question states that it takes a object .210seconds to cover 1.35meters. So with that given information i have to find what height the object falls from. Well a given is the objects acceleration is 9.8m/s squared
Im sorry that i cant really provide any work, im definately not trying to freeload, and i do want to learn how to do this stuff. I just need someone to walk me through it.
