A motocross rider performs a triple jump maneuver from point Bto point C. The combined mass of the rider and motorcycle is165 kg. The curvature of the ramp between point A and point Bis described by the function y = 0.64x² - 1.6x, where the originis at point A and both x and y are measured in meters.(a) Show that the angle of the ramp at point B isapproximately 57.995°.(b) In order to land at point C, determine the speed at whichthe rider must leave the ramp at B.Motorcycle jump(https://www.bertsmegamall.com/blog)(c) If the rider's speed increases at a constant rate from 5.5 m/s at point A to the computed speedat point B found in part (b), determine the motorcycle's constant tangential accelerationknowing that the arc length traveled along the ramp from A to B is 3.3 meters.(d) At point B just before leaving the ramp, determine the normal force exerted by the ground.on the motorcycle and the traction force (forward force parallel to the surface) between themotorcycle and the ground. (Treat the motorcycle as a particle.)y (m)x (m)y = 0.64x²-1.6x2.5 mB6.5 m

SHOW THE SOLUTION: One morning, Connie walks from her house to go to a store that is 500 ft, S 40o W from her house. She starts walking 120 ft, SW; then continues walking 100 ft, 10o S of E; then sees a friend who is 700 ft, 30o N of E from where she is. What is her friend’s location, (magnitude and direction) relative to her house? (Answer: 667.54 ft, 21.79o N of E) From her friend’s location, how far and in what direction should Connie walk to finally get to the store? (Answer: 1133.08 ft, 33.83o S of W)
