CP Angled Launch Quiz Review

A projectile is launched at an angle above the horizontal. Neglecting air resistance, what are the projectile's horizontal and vertical accelerations when it reaches its maximum height?

• Both the horizontal and vertical accelerations are zero.

• The horizontal acceleration is zero and the vertical acceleration is -10 m/s²

• The horizontal acceleration is -10 m/s² and the vertical acceleration is zero.

• Both the horizontal and vertical accelerations are -10 m/s².

Compared to an arrow fired at 60°, an arrow fired at 45° has a:

• longer flight time and longer horizontal range.

• longer flight time and shorter horizontal range.

• shorter flight time and longer horizontal range.

• shorter flight time and shorter horizontal range.

What happens to the magnitude of the ball's vertical velocity during the time interval that the ball is in the air?

• It goes from positive to zero to negative

• it goes from negative to zero to positive

• It remains the same.
