ok i tried using x=VoXT + 1/2axt^2 but i don't think it applies because there is no time involved in part a

please i have no idea where to start and what equation to use!

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. (a) How...

Homework Statement A left-handed pitcher at sea level throws a baseball at a 45o angle with an initial speed of 19 m/s. The time for the ball to reach its highest point can be found from the data and known constants using which equations? Solve for the time. Homework Equations V^2 =...

ya i tried both sin and cos and timesed them by the gravity, and then i divided it by the length and part a was still wrong?

ok obvisouly I am doing something wrong here, does anyone have a list of formulas for projectile motion. I don't seem to have any in the textbook, and mastering physics is just giving me questions, no formulas.

ok for the acceleration i took the cos(37)*9.8 and came up with 7.82, is this even close to what i need to be doing?

thanks for the speedy reply, i will work on this for a bit now and see what i come up with

That can be determined by the angle with respect to gravity How do i know when to use sin cos or tan, and what one would i use here?

Homework Statement A child slides down a frictionless 3.1 -long playground slide tilted upward at an angle of 37. At the end of the slide, there is an additional section that curves so that the child is launched off the end of the slide horizontally. Part A How fast is the child moving at...

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 I am 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...

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

well you could have broke it down a little better and explained what i needed to do instead of thowing a formula at me and sayin use it

wow this is a great forum, i really appreciate all the replys I am getting and the help! You guys are great!

dont worry i feel the same way
