Es Test: Flag this Question 5)
Base your answer on the information below.
A ball is projected vertically upward from the surface of the Earth with an initial speed of +49
meters per second. The ball reaches its maximum height in 5.0 seconds. (Disregard air
resistance.)
A
What is the maximum height reached by the ball?
A)
24.5 m
B
49.0 m
C)
122.5 m
D)
245 m

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
