Yosemite Sam has a weight of 784 N when standing by the ocean on the mysterious planet LooneyToon. He climbs to the top of a nearby mountain and has a weight of 783 N. A) Determine the altitude of the mountain in terms of the radius of the planet (example answer: h = 0.025 Rplanet or 2.5% of planet radius). You do not know the planet's mass or radius. B) Based on your answer what would the height be on the planet Earth which has a radius of 6380 km? Would you be able to lose 1 N of weight climbing Mt Everest (8.84 km)? C) Based on your answer what would the height be on Mars which has a radius of 3389.5 km? Would you be able to lose 1 N of weight climbing Olympus Mons (21.9 km)? Could you even weight 784 N on Mars?

Tasmanian Devil orbits the Earth in geosynchronous orbit just like a cell phone or telecommunications satellite does. Determine the speed of his ship and the radius of his orbit.

Babs Bunny drives a 1 200 kg car at 20 m/s around a frictionless banked curved road of unknown radius r km and angle 30o above the horizontal. A) Determine the radius of the curve. B) What speed would be safe for Babs if the road was flat with an ideal coefficient of friction of 0.97?

The Warner Brothers and Sister - Yakko, Wakko, and Dot drive a 250 kg bike around a banked curved road of radius 50.0 m, coefficient of friction 0.98 and angle 20.1o above the horizontal. Determine the tangential velocity of the bike if the force of friction keeps the bike from moving A) up the hill B) down the hill C) up the hill and there is a micro-singularity or miniblack-hole of mass 1015 kg at the centre of the curve D) down the hill and there is a micro-singularity or mini-black-hole of mass 1015 kg at the centre of the curve.
