Hi, I really need help with my homework!!! I had a home work, it is like: I have a data table, that has Initial Position: 1.652m from the sensor Final Position: 0.977m from the sensor Initial Velocity: 0.003m/s Final Position: 1.366m/s Angle: 27 degrees g = -9.8m/s^2 U represent the variable for coefficient of friction The question asks me to find the coefficient of friction, by using the formula according to the potential energy, it's like gh= v^2+ UcosAngle*d*g I'm so confused!! Please help me@!!!! Thank you in advance!!!
