Aspaceship is projected vertically upward from the earth's surface with an initial speed of 7.51 km/s, but unfortunately does not have a great enough speed to escape earth's gravity. what maximum height does the spaceship reach (in m)? ignore air resistance.

Plss anybody know how to do this? ? i need the answers from a through d

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
