In Fig. a rescue plane flies at 198 km/h (= 55.0 m/s) and constant height h 500 m toward a point directly over a
victim, where a rescue capsule is to land.
What should be the angle o of the pilot's line of sight to
the victim when the capsule release is made?

Assuming weightless pulleys and 100% efficiency, what is the minimum input force required to lift a 120 n weight using a single fixed pulley?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
