6 7 A point The projectile velocity is the highest velocity that will be reached by a falling object. True False I point When an object falls It is reacting to the force of gravity. True False 1 point Jane is on a merry-go-round that is moving at a constant speed.Her velocity is also constant. True like 1 point The momentum of 5,000-be truck that is standing still is greater than the momentum of 33000-18 truck that is also at rest. True False

Answer 1

1. False 2. False 3. True 4. False

Answer 2

## For the first statement: ### The formula for momentum is given by \( \mathbf{p = mv} \), where \( p \) is momentum, \( m \) is mass, and \( v \) is velocity. ## Since both trucks are at rest, their velocities (\( v \)) are 0. Therefore, their momentums are also 0, regardless of their masses. This makes the statement false. ## For the second statement: ### Projectile velocity typically refers to the initial velocity of a projectile. The highest velocity reached by a falling object without air resistance is its terminal velocity, which is not the same as projectile velocity. However, the statement may be misleading as it seems to confuse projectile velocity with terminal velocity. In physics, the term "projectile velocity" is not used to describe the highest velocity reached during free fall. The statement is false because it inaccurately describes projectile velocity. ## For the third statement: ### When an object falls, it is indeed reacting to the force of gravity. This is a fundamental principle of physics, where gravity is the force that attracts a body towards the center of the earth, or towards any other physical body having mass. True. ## For the fourth statement: ### If Jane is on a merry-go-round moving at a constant speed, her speed (magnitude of velocity) is constant. However, because the direction of her motion is continually changing (circular motion), her velocity is not constant. Velocity is a vector quantity that includes both speed and direction. Therefore, the statement is false.
