While a roofer is working on a roof that slants at 32° above the horizontal, he accidentally nudges his 73N toolbox, causing it to start sliding downward, starting from rest. If it starts 5m from the lower edge of the roof, how fast will the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18N? Answer: 5.27m/s

A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d = 4.15m, and x and y are measured in meters as usual. Now suppose the blocks starts on the track at x = 3.35 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 4.05 m/s 7.28 m/s 5.15 m/s 4.97 m/s

previous problem: A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 3.85 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -1.99 m. What will the block s speed be when it reaches x = 0? New problem Same type of track as in the previous problem, this time with d = 4.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 7.57 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? -3.72 m 3.72 m 2.92 m -2.92 m

A helicopter is dellvering food in an emergency situation, where it is difficult to land. The engineer is tasked with determining what heights the package could be dropped without breaking. She knows that if the package strikes the ground faster than the critical speed of 62.0mph, then the package will break. Neglect drag At what height would the package hit the ground with the critical speed (in given units? Could the package be safely dropped from a height of 30m? yes no
