A roller coaster with a mass of 300 kg is at the top of a 75.0 m hill. It rolls down the hill on very low friction wheels and climbs up to the top of a 45.0 m hill. You must show all work to receive credit! Find: (a) the speed of the thing at the bottom of the first hill

(b) its speed at the top of the second hill.

Thank you for your time and hard work!

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
