1. The problem statement, all variables and given/known data 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 2. Relevant equations [tex]\Delta[/tex]y =Vo*t - .5 1/2gt^2 Vx = Vox + .5at^2 3. 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?
