If you are trying to find the horizontal component (Vx) of a projectile's velocity, what trigonometry function would you use?

• Cosine

• Sine

• Tangent

• Traxoline

A projectile is launched at a 50 degree angle. What can I do to increase the time the projectile is in the air?

• Launch at a greater angle

• Launch horizontally

• Launch at a smaller angle

• Don't launch the projectile

A projectile is launched horizontally at 25 m/s from a tower 30 m high. What can I do to increase the time the projectile is in the air?

• Launch with a greater velocity

• Launch downward instead of horizontal

• Launch with a smaller velocity

• Launch from a higher tower

What effect does the mass of a projectile have on the time it's in the air? (Neglecting air resistance)

• The lighter the projectile, the greater the time in the air

• The heavier the projectile, the greater the time in the air

• It has no effect

• The lighter the projectile, the less the time in the air

The vertical acceleration

of any projectile ...

• is always 9.8 m/s².

• is always -9.8 m/s².

• depends on the launch velocity.

• depends on the angle of launch.
