Question 13solve h 3) A projectile is fired 2.5n angle of 30.0 ° above the horizontal on a long flat firing range. Determine (a) theal time in the air, (b) the total horizontal distance covered, and (c) the maximum heightached by the projectile above the ground.12. (Ch 4) Passengers riding in the Great Six Flags Air Racer are spun around a tall steeltower. At top speed the planes fly at a 65.0° bank approximately 30.0 m from the tower.In this position the support chains make an angle of 65.0° with the vertical. Assuminguniform circular motion, (a) draw a free body diagram, (b) write out the force componentequations for each axis, (c) calculate the speed of the planes, and (d) determine thetension in the cable.13. (Ch 5) You are holding a book against a wall by pushing up at an angle with your hand.Your push makes an angle of 0 with the wall. The mass of the book is m, and thecoefficient of static friction between the book and the wall is µ. (a) Draw the "free-body"diagram for the book. And then write out the sum of force components in x and y. (b)Rearrange equations to find the magnitude of the push you must exert to (barely) hold thebook stationary. In other words, find the force F in terms of all the other given variables.(c) Think Calculus. Determine for what value of the angle is the magnitude of the requiredpush as small as possible (minimum)?14. (Ch 5). An Aston Martin Vantage has a mass of about 1500. kg. A highway curve has aradius of r = 500. m and is designed for a traffic speed of 15.0 m/s. (a) Assume the curveis banked, draw a force diagram for the car and label the x and y axis, normal force,weight, and friction down the incline. (b) Write out the force equations for the x-direction, for the y-direction, and for friction. (c) Relate v2/(rg) as a function of 0. (d) Ifno friction is needed, what angle is the road banked at for the designed speed? (e) Iffriction is present, and a driver is traveling at twice the designed speed, determine thecoefficient of friction directed along the slope of the banked road in order to round thecorner without skidding.
