PHYSICS HOMEWORK HELP
arrite.. so i am calling out for a bit of help on these simple physics problems.. no matter ho many times and way i do it.. the answers are the same and wrong.. so if you could help me out, that'd be great.
here are the equations
t (Vinitial + V) =X
2
X=Xinitial+(Vinitial)(t) + .5at^2
V=Vinitial+at
V^2 = Vinitial + 2a(X-Xinitial)
V is final velocity.
a is acceleration (usually due to gravity.. 9.8m/s^2)
X is displacement
t is time
(and ^2 means squared)
4. A ball has an initial speed of 15m/s the acceleration due to grav. is 9.8m/s^2. What will the position be after 2.2 secs?
7. The acceleration due to gravity on the moon is about 1/6 its value on earth. If a baseball reaches a height of 59m hen thron upward by someone on earth, what height would it reach when thrown in the same way on the surface of the moon?
