AP Callegeloard AP PHYSICS C: MECHANICS Test Booklet Unit 3 Progress Check: FRQ 1. Read each question carefully. Show all your work for each part of the question. The parts within the question may not have equal weight. TA stelais 10 m B A ski jumper starts from rest from point A at the top of a hill that is a height h1 above point B at the bottom of the hill. The skier and skis have a combined mass of 80 kg. The skier slides down the hill and then up a ramp and is launched into the air at point C that is a height of 10 m above the ground. The skier reaches point C traveling at 42프. (a) Calculate the height h1. (b) Calculate the speed of the skier as the skier reaches point B. (c) Is the work done by the gravitational force on the nint B eor
