Chapter 5, Problem 26P
(II) A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28° incline (Fig. 5–36). After sliding down the 110-m long incline (on which the coefficient of kinetic friction is μk = 0.18), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which μk = 0.15) and comes to rest after a distance x. Use Newton’s second law to find the snowboarder’s acceleration while on the incline and while on the flat surface. Then use these accelerations to determine x.

A frictionless incline is 5.00 m long (the distance from the top of the incline to the bottom, measured along the incline). The vertical distance from the top of the incline to the bottom is 2.26 m. A small block is released from rest at the top of the incline and slides down the incline.
(i) How long does it take the block to reach the ground?
A body weighing 40 lb starts from rest and slides down a plane at an angle of 30° with the horizontal for which the coefficient of friction µ = 0.30. (1) How far will it move during the third second? (2) How long will it require for it to move 60ft?
(III) Early test flights for the space shuttle used a “glider”(mass of 980 kg including pilot). After a horizontal launchat 480 km/h at a height of 3500 m, the glider eventuallylanded at a speed of 210 km/h (a) What would its landingspeed have been in the absence of air resistance? (b) Whatwas the average force of air resistance exerted on it if itcame in at a constant glide angle of 12° to the Earth’s surface?
