Homework Statement
a track is inclined in such way that the velocity of the metal ball is 60 cm/s at 25 degree below the horizontal. mathematically determine the total x displacement of the metal ball.
weight of ball: 65grams
height from floor to the end of the track: 76.15cm
velocity of the ball is 60.cm/s at 25 degree
Homework Equations
[tex]\Delta[/tex]y =Vo*t - .5 1/2gt^2
Vx = Vox + .5at^2
The Attempt at a Solution
I used the first equation to find time.
-76.15 = .5*-9.8t^2
t=.394s
deltaX = .6m/s*cos(-25).3942 + .5(-9.8).3942^2
i got delta X to be -54.7cm
is it suppose to be negative?
Could someone help me set this up right?
