In one of your experiments, you will roll a marble down a ramp to provide an initial horizontal velocity. suppose you start the marble at rest (vo = 0 m/s) and it travels a distance of, d, down the ramp. use 1-d kinematics to predict the velocity of the ball (vf ) at the bottom of the ramp. hint: the acceleration of the ball down the ramp is 9.81*sin(θ) m/s2 where θ is the angle of the ramp. record you answer in variables (you will calculate the velocity with magnitudes when you perform the experiment).
