8. A marble rolls down a 1.55 meter ramp that is at an angle (to the positive x-axis) of 150.0". The marble is at rest at the top of the ramp and reaches the bottom of the ramp in 1.95 seconds. Assume constant acceleration 1.55 m - 150 a. What is the average velocity of the marble? b. What is the vertical average velocity of the marble? c. What is the horizontal average velocity of the marble? d. What is the acceleration of the marble? e. What is the marbles' vertical acceleration component?
f. What is the marble's horizontal acceleration component? & What is the marble's instantaneous velocity at the bottom of the ramp? h. What is the marble's vertical instantaneous velocity component? 1 What is the marble's horizontal instantaneous velocity component? j. Is this ramp on earth or some other planet? Why?
