Problem Solving 1. What is the acceleration of a car racer that accelerates from 0 to 90 m/s in 6.0 seconds? 2. What is the acceleration of a truck driver moving at 18 m/s and applies the brakes and stops in 4.0 seconds? 3. An automobile accelerates from rest to 8.8 m/s in 3.0 seconds using the first gear then changes to second gear. The automobile reaches 22.0 m/s and is shifted into third gear. After 7.0 seconds in third...

The planetary gear system is used in car transmissions. There is sun gear S, planet gears P and the ring gear R. By locking (fixing/grounding) certain gears you can have different gear ratios and 40 mm OR car speeds a) If the ring gear is held fixed, i.e. aR -0, and the sun gear is rotated at ws - 5 rad/s, find the angular velocity, ωΡ。f the planet gears and the output shaft A. b) If the sun gear is...
6. Gear A rotates with an angular velocity of 0,= 20 rad/s, where 0, is the angular displacement of gear A, measured in radians. Gears A, B, C, and D have radii of 20 mm, 50 mm, 25 mm, and 100 mm, respectively. When e = 2 rad , Find: i) The angular velocity of gear A 11) The angular acceleration of gear A 111) The angular velocity of gear B iv) The angular acceleration of gear B The angular...
