Projectile Motion and Time of Flight Quiz

What is the initial velocity of the ball in the given example?

• 25 m/s

• 15 m/s

• 10 m/s

• 20 m/s

What is the angle of projection of the ball?

• 45 degrees

• 90 degrees

• 30 degrees

• 60 degrees

What does the capital T represent in projectile motion?

• Time to reach the ground

• Total time of flight

• Time to reach the peak

• Time to reach maximum height

How is the time of flight related to the smaller t?

• T is twice the smaller t

• T is three times the smaller t

• T is half of t

• T is equal to t

What is the final vertical velocity of the ball at maximum height?

• 5 m/s

• 0 m/s

• 20 m/s

• 10 m/s

What is the equation used to find the time taken to reach maximum height?

• s = ut + 0.5at^2

• v^2 = u^2 + 2as

• s = vt - 0.5at^2

• v = u + at

What is the displacement in the vertical direction for the entire motion?

• 5 meters

• 10 meters

• 20 meters

• 0 meters

Which equation is used to derive the time of flight using displacement?

• s = ut + 0.5at^2

• s = vt - 0.5at^2

• v^2 = u^2 + 2as

• v = u + at

What is the calculated time of flight for the given example?

• 1.5 seconds
