Will give Need help ASAP PL assuming bird flies at height of 72m, how fast should he fly to hit bucket at 63m from start of field. gravity is -9.8m/s^2 no air resistance, drops thing at start of field. what is his speed/velocity

Ais useful when you need a simple machine to you separate two things. a. lever b. screw c. pulley d. wedge

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
