Unformatted text preview: Chapter E - Problems Blinn College - Physics 2425 - Terry Honan Problem E.1 (a) What is the centripetal (radial) acceleration of a point on the earth's equator? (b) Give an expression for the centripetal acceleration as a function of the latitude angle, q L . What is this at the latitude of Bryan, Texas, at q L = 30.7 °? (c) What are the speeds of a point at the equator and at Bryan, Texas due to the eaarth's rotation? (d) The earth's rotation is slowing at a rate of 2.2 s every 100,000 years.. „ T „ t = D T D t = 2.3 s 100,000 years What is the (very small) tangential component of the acceleration of a point on the earth's equator? Hint: use the chain rule. „ „ t 2 p r T = - 2 p r T 2 „ T „ t Problem E.2 A car drives around a 200 m radius circle with a speed that decreases uniformly from 30 m ê s to 20 m ê s in 8 s. At the instant the speed is 25 m ê s then: (a) what is the centripetal acceleration, (b) what is the tangential acceleration and (c) what is the magnitude of the acceleration?...
