Test your understanding of lesson 5.4: projectiles from a height and on inclined ground with 5 practice questions.

Practice Questions

Question 1

A projectile is launched from a height of $20$ meters at an angle of $45$ degrees to the horizontal. What is the vertical component of the initial velocity if the initial speed is $30$ m/s?

Question 2

If a projectile is launched horizontally from a height of $30$ meters, what is the time of flight until it hits the ground? (Assume $g = 9.8$ m/s²)

Question 3

A projectile is launched with an initial velocity of $20$ m/s at an angle of $60$ degrees. What is the horizontal component of the projectile's velocity?

Question 4

What is the range of a projectile launched at an angle of $45$ degrees from a height of $15$ meters with an initial velocity of $30$ m/s?

Question 5

A projectile launched from a height of $5$ meters has an initial vertical speed of $12$ m/s. How long will the projectile be in the air before it reaches the ground? (Neglect air resistance and use $g = 9.8$ m/s²)
