-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(?) m/s2 where ? is the angle of the ramp. Record you answer in variables (you will calculate the velocity with magnitudes when you perform the experiment).
-Use the kinematic equations to derive a general equation for the time it takes a ball dropped from rest at vertical height, h, to reach the ground.
??????????????????????????????????????????????? h = (1/2)gt2
-?Use the result from Question 2 to write a general equation for the distance travelled by a projectile that is rolling of a table of height, h, with a horizontal speed, v0x.
Hint: The velocity at the beginning and end of the motion has the same magnitude, but opposite direction.
