Projectile Motion Problem Solving Challenge

The video tutorial addresses a physics problem involving constant acceleration due to gravity. It explains how a football kicked with specific initial velocities in horizontal and vertical directions travels in a parabolic arc. The tutorial covers the calculation of time the football stays in the air, as well as its maximum horizontal and vertical displacements. Key concepts include the independence of horizontal and vertical velocity components, the effect of gravity on vertical motion, and the use of kinematic equations to solve for time and displacement.

What is the initial horizontal velocity of the football?

• 10 m/s

• 12 m/s

• 15 m/s

• 22 m/s

What is the initial vertical velocity of the football?

• 22 m/s

• 10 m/s

• 12 m/s

• 15 m/s

What shape does the trajectory of the football follow?

• Linear

• Circular

• Parabolic

• Elliptical

What happens to the vertical velocity at the maximum height of the football's trajectory?

• It becomes zero

• It doubles

• It remains constant

• It reverses direction

Why does the horizontal velocity remain constant throughout the football's flight?

• Because of air resistance

• Because there is no horizontal acceleration

• Because of the initial kick

• Because of gravity

What is the value of the acceleration due to gravity used in the calculations?

• 9.81 m/s²

• 10 m/s²

• 8.9 m/s²

• 12 m/s²

How long does the football stay in the air?

• 2.24 seconds

• 5.0 seconds

• 3.5 seconds

• 4.49 seconds

What is the horizontal displacement of the football?

• 60.1 meters

• 40.5 meters

• 50.2 meters

• 53.82 meters

At what point in the trajectory is the maximum vertical displacement achieved?

• At the end

• At the highest point

• At the start

• At the midpoint

What is the maximum vertical displacement of the football?

• 30.2 meters

• 24.67 meters

• 20.5 meters

• 35.1 meters
