A kid on a bike with a combined mass of 100 kg. goes 7 m/s at the top of a hill. The hill has a vertical drop of 50 m. How fast is the kid and bike going when they reach the bottom of the hill?( no friction) 1. c. d. O 27 m/s 23 m/s O 32 m/s O 980 m/s

PRINTER VERSION 1 BACK NEX Z Your answer is partially correct. Try again. In the figure, a frictionless roller coaster car of mass m = 832 kg tops the first hill with speed vo = 19.0 m/s at height h = 44.0 m. What is the speed of the car at (a) point A, (b) point B, and (c) point C? (d) How high will the car go on the last hill, which is too high for it to cross? Use g=9.81 m/s2.

The most wonderful thing about Tiggers is that their tops are made out ofrubber and their bottoms are made out of springs. Suppose Tigger wants to reach some honey located a height ℎ above the ground. If Tigger has a mass of m and his tail has a spring constant of k, how much must he coil his tail in order to reach the honey? A. (mgh/k) B. = √(mgh/k) C. (2mgh/k)D. √(2mgh/k)E. None of these
