a) if an object has an initial velocity of 2.6 m/s [East] and accelerates at 1.5 m/s2 [West] for 8 seconds, solve for it’s final velocity and displacement b) if an object is dropped from a window that is 72m above the ground, how long will it take to reach the ground and how fast will it be moving the instant before it hit the ground?

a) describe the energy transformation principles that we use when we use the conservation of mechanical energy formula. b) if a 2.5 kg mass falls from a 50m high window with an initial velocity of 1.5 m/s [down], use conservation of mechanical energy to solve for i) the total mechanical energy in the system. ii) the speed of the object when is has fallen to a height of 30m Desmos online calculator
