1. ### Newtons Law

ok i tried using x=VoXT + 1/2axt^2 but i dont think it applies because there is no time involved in part a
2. ### Newtons Law

please i have no idea where to start and what equation to use!
3. ### Newtons Law

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...
4. ### Will you check my work?

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 =...
5. ### Frictionless Slide (mastering Physics)

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?
6. ### Frictionless Slide (mastering Physics)

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.
7. ### Frictionless Slide (mastering Physics)

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?
8. ### Frictionless Slide (mastering Physics)

thanks for the speedy reply, i will work on this for a bit now and see what i come up with
9. ### Frictionless Slide (mastering Physics)

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?
10. ### Frictionless Slide (mastering Physics)

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...
11. ### Homework Due Tonight (jan 27)

13. ### Homework Due Tonight (jan 27)

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
14. ### Homework Due Tonight (jan 27)

wow this is a great forum, i really appreciate all the replys im getting and the help! You guys are great!
15. ### Introduction to Physics HELP. I AM LOST

dont worry i feel the same way
