Unformatted text preview: Recitation 5 1/14 Phys 218 Physics Topics Kinematics constant acceleration no acceleration (a=0) Forces constant acceleration static equilibrium (no acceleration) These topics for both: Linear Motion Circular Motion Recitation 5 2/14 Phys 218 Example 1 A wheel has a radius of 2 meters. If the wheel is spinning at 60 revolutions per minute, (a) how fast is a point on the edge of the wheel moving and what is its acceleration? (b) How fast is a point moving and what is the acceleration for a point at a radius of 1.5 m? (a) v = __________ a c = __________ (b) v = __________ a c = __________ 12.56 m/s 78.96 m/s 2 9.42 m/s 59.2 m/s 2 Recitation 5 3/14 Phys 218 Example 2 A person with a mass of 60 kg is driving down a flat road at a constant velocity of 5 m/s. (a) What is the normal force on the person? (b) If the person drives over a hill with a radius of curvature of 10 m, what is the normal force on the person at the top of the hill? (a) N level = __________ (b) N top = __________ 588 N Recitation 5 4/14 Phys 218 Question 1 (Example 2 continued) A person with a mass of 60 kg is driving down a flat road at a constant velocity of 5 m/s....
