What is the equation for the horizontal velocity of a projectile?

• v = d/t

• v = at

• v = da

At what point in a projectile's motion is its velocity equal to zero?

• At the highest point of its trajectory

• At the lowest point of its trajectory

• At the beginning of its trajectory

What is the equation for the vertical displacement of a projectile?

• d = v*t

• d = (1/2)at^2

• d = (v_i + v_f)/2 * t

At what angle should a projectile be launched to achieve maximum range?

• 45 degrees

• 60 degrees

• 90 degrees

What is the range of a projectile?

• The maximum height it reaches

• The distance it travels horizontally before hitting the ground

• The total distance it travels from launch to impact

What is the acceleration due to gravity?

• 9.8 m/s^2

• 5.5 m/s^2

• 6.7 m/s^2

How does air resistance affect the motion of a projectile?

• It increases the projectile's speed

• It decreases the projectile's speed

• It has no effect on the projectile's speed

How does increasing the angle of launch affect the maximum height of a projectile?

• It has no effect

• It increases the maximum height

• It decreases the maximum height

What is the equation for the time of flight of a projectile?

• t = 2*v_i/g

• t = (v_i + v_f)/g

• t = d/v

What is the equation for the maximum height of a projectile?

• h = v_it - (1/2)gt^2

• h = (v_i^2sin^2(theta))/(2g)

• h = (v_i^2)/(2g)
