In one of your experiments, you will roll a marble down a ramp to provide an initlal horizontal velocity. Suppose you start the marble at rest (EL: 0 mfs) and lttravels a distance of, 0', down the ramp. Use 1-D kinematics to predict the velocity of the ball (3') at the bottom of the ramp. int: the acceleration of the bell down the ramp is 9.81 *sin(6) m-'s= where 6 is the angle of the ramp. Record you answer in variables (you will miom'ate the velocity with mime when youperfonnreexpedment}. 2. Use the kinematic equations to derive a general equation for the time it takes a ball dropped from rest at verlioal helght. h. to reach the ground. 3. Use the result from Question 2 to write a general equation for the distance travelled by a projectile that is rolling off a table of height, h, with a horizontal speed, V.. 13.)
