Rack Ramp
Please help with physics problem!?
Here is the link to the photos: After http://i599.photobucket.com/albums/tt71/Adriankaye/walk1060.gif you pick up a spare, your bowling ball rolls without slipping toward the ball rack with a linear speed of v = 3.35 m / s, as shown in Fig. To achieve the rack, ball up a ramp that rises through a vertical distance of h = 0.511 m. What is the linear velocity of the ball when it reaches the top of the ramp?
Total energy before ramp is translational KE + rotational KE (0.5. M. V ^ 2) + (0.5. I. W ^ 2) w = v / r I = (2 / 5) m. r ^ 2 Total energy is (0.5. m. v ^ 2) + (0.2. M. V ^ 2) = 0.7. m. v ^ 2 the total energy after the ramp is 0.7. m. (v new) ^ 2 + mg h = energy after energy before 0.7. m. 3.35 ^ 2 = (0.7. M. V ^ 2) + (m. 9.8. 0.511 m) cancel Reorganize ((0.7. 3.35 ^ 2) – (9.8. 0.511)) / 0, 7 = v ^ 2 v = 2.02 m / s
