CURVILINEAR: Cheezy placed an order for 16 cubic meters of sand. The sand was ejected from a dump truck at a 50-degree angle, with an initial velocity of 2 feet per second. Calculate the radius of curvature of the trajectory at the direction point 1m below point A. with Illustration
A Ferris Wheel, with radius 50 ft., turns counterclockwise one revolution every 18 seconds. Bryce stands at a point 120 ft. from the base of the wheel on the “upward motion” side and off to one side at an angle of 20°. The wind is blowing toward the Ferris Wheel, essentially into Bryce’s face, at an angle 30° to the base of the wheel. This wind results in an acceleration of 12 ft/s2 . At the instant Susan is at point A (3 o’clock on the wheel), Bryce throws a ball at the Ferris Wheel, releasing it from the same height as the bottom of the wheel. If the ball’s initial speed is 110 ft/sec and it is released at an angle of 60° with the horizontal, does Susan have a chance to catch the ball? Explain why/why not

5. A sprinkler rotates around fixed Point C. The nozzle on Arm A has broken off. So, water exits Arm A in the radial direction, relative to the sprinkler at 2 m/s and the radial velocity of the water is increasing at 0.5 m/s². The sprinkler arms are rotating around Point Cat = 6 rad/s, and because the nozzle has broken, it is decelerating with Ö= -1 rad/s². At that moment, what are the radial (vr) and theta (ve) components of velocity of the water exiting the sprinkler at Point A? b.
