Se lanza un objeto con velocidad vertical de 25m/s y horizontal de 15m/s
a. ¿Cuál es la altura máxima que alcanza el objeto?
b. ¿Cuál es el alcance horizontal del objeto?

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.
