1.hi, im new to this forum and i have a question regarding my final physics lab: A solid spherical ball, R= 1.4 cm and m=95 grams, is released from point A(1m above the). After travelling through the loop, the ball exits the set up as a projectile and land at point B with the horizontal distance of X= 37 cm. the picture of the setup is here: 2. i have to find the theoretical distance x, but im not sure how to do this... 3. The attempt at a solution I tried finding the velocity at the end of the track by saying mgh = K.E.r+K.E+mgh(loop)+mgh(end of track) and i get the velocity once the ball leaves the track to be .843m/s. i think this seems to easy though, is it? Im stuck on how to even start this and this is our final lab so we have to use all of our physics we've learned so far. Can someone give me a hint on how to start?
