Base your answers to questions 71 through 75 on the following information. A ball of mass m is thrown horizontally with speed v from a height h above level ground. [Neglect friction.] 71. If the height above the ground from which the ball is thrown was increased, the time of flight of the ball would (1) decrease (2) increase (3) remain the same 72. If the initial speed of the ball was increased, the time of flight of the ball would (1) decrease (2) increase (3) remain the same 73. If the initial speed of the ball was increased, the horizontal distance traveled by the ball would (1) decrease (2) increase (3) remain the same
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.

71. If the height above the ground from which the
ball is thrown was increased, the time of flight
of the ball would
(1) decrease (2) increase (3) remain the same
72. If the initial speed of the ball was increased, the
time of flight of the ball would
(1) decrease (2) increase (3) remain the same
73. If the initial speed of the ball was increased, the
horizontal distance traveled by the ball would
(1) decrease (2) increase (3) remain the same
74. As time elapses before the ball strikes the
ground, the horizontal velocity of the ball
(1) decreases
(2) increases
(3) remains the same

traveled by the ball in the absence of air
resistance, the total horizontal distance
traveled by the ball with air resistance is
(1) shorter
(2) longer
