22) You were trying to put holiday decorations on the roof, but didn't realize that the roofhad a layer of black ice making the it completely smooth. Taking the pitch (angle) of theroof as 26.6°, find your acceleration as you slip towards the edge of the roof. Hint: Don'tforget to start with a clear force diagram!26.6

You have been asked to design an escape ramp for trucks in a downhill 40 mph zone. Assuming a truck has lost control at 60 mph and the friction coefficient of your sand/earth ramp is .30, what angle should you make the ramp (nearest degree) if you only have 250 feet horizontal? Hint: you may have to solve this iteratively.
1. You are tasked with designing the runway on an aircraft carrier. The minimum speed for the F/A18 Hornet is 200 mph. The Hornet weighs 40,000 lbf and its twin engines provide a thrust of ~40,000 lbf combined, providing a max acceleration of 1g.a. How long must the deck be to takeoff unassisted? Give the answer in ft. b. This is most likely longer than your typical ~450 ft carrier. What acceleration must you achieve with both the engines and with a catapult system together to reach the required minimum speed by the end of the deck? c. What net force (combined engines and catapult) must be applied to the plane to get the acceleration in b? d. Do you think the plane will be able to use disk brakes on its tires to stop when landing?Use your knowledge of friction to make your argument. Also know that their coefficient of friction is ~1.
