The range of a projectile depends not only on v0 and θ but also on the value g of the free-fall acceleration, which varies from place to place. in 1936, jesse owens established a world's running broad jump record of 8.09 m at the olympic games at berlin (where g = 9.8128 m/s^2). assuming the same values of v0 and θ, by how much would his record have differed if he had competed instead in 1956 at melbourne (where g = 9.7999 m/s2)?

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
