Question

Which of the following statements are true of the vertical motion of projectiles? True or False?

A. The vertical component of a projectile's velocity is constant.

B. The vertical component of a projectile's velocity changes at a constant rate.

C. The magnitude of the vertical velocity of a projectile changes by 9.8 m/s each

second.

D. The vertical velocity of a projectile is 0 m/s at the peak of its trajectory.

E. The final vertical velocity of a projectile is always equal to the initial vertical

velocity.

F. The vertical acceleration of a projectile is 0 m/s2 when it is at the peak of its

trajectory.

G. The peak height to which a projectile rises above the launch location is dependent

upon the initial vertical velocity.

H. As a projectile rises towards the peak of its trajectory, the vertical velocity will

decrease; as it falls from the peak of its trajectory, its vertical velocity will increase.

A) false

B) True

C) True

D) True

E) True (magnitudes are same)

F) Flase

G) True

H) True (magnitude increases)
