I am currently learning about kinematics in my physics class. For one of the questions, it asks me to solve a question that asks me to find the magnitude of acceleration. I have found answers ranging between 3 and 4, but everytime I put my answer into Webassign it is wrong. I was wondering how I would find the magnitude of acceleration given the time and distance. Thank you
POSSIBLE POINTS: 7.32 Julietta and Jackson are playing miniature golf.
