Question

manny is playing basketball and jumps in the air to make a shot. match each of newtons laws of motion to the statement it best describes. newtons first law of motion newtons second law of motion newtons third law of motion the basketballs horizontal velocity remains constant until it hits the backboard. when manny jumps, the ground exerts an upward force on manny that is equal to the downward force that manny exerts on the ground. in order to accelerate upward, manny must exert a force on the ground that is greater than his weight.

Explanation:

• Newton's first law (law of inertia) states that an object in motion will stay in motion with a constant velocity unless acted upon by an external force. The basketball's horizontal - velocity remaining constant until it hits the backboard is an example of this.
• Newton's third law states that for every action, there is an equal and opposite reaction. When Manny jumps, the ground exerts an upward force on Manny equal to the downward force Manny exerts on the ground.
• Newton's second law is $F = ma$. To accelerate upward, Manny must exert a force on the ground greater than his weight to create a net upward force for acceleration.

Answer:

• The basketball's horizontal velocity remains constant until it hits the backboard: Newton's first law of motion
• When Manny jumps, the ground exerts an upward force on Manny that is equal to the downward force that Manny exerts on the ground: Newton's third law of motion
• In order to accelerate upward, Manny must exert a force on the ground that is greater than his weight: Newton's second law of motion
