Projectile Motion Concepts

This video tutorial covers projectile motion problems, focusing on calculating maximum height and range. It includes three problems: a ball rolling off a cliff, a ball kicked from the ground, and a ball kicked from a building. Each problem is solved step-by-step, with explanations of the formulas used. The video also provides tips on drawing diagrams and using a formula sheet for solving projectile motion problems.

What is the initial speed of the ball in the first problem discussed?

• 15 m/s

• 10 m/s

• 25 m/s

• 20 m/s

How long does it take for the ball to hit the ground in the first problem?

• 6 seconds

• 5 seconds

• 7 seconds

• 4 seconds

What formula is used to calculate the range of a projectile moving horizontally?

• Range = Vy * T

• Range = Vy * G

• Range = Vx * T

• Range = Vx * G

In the second problem, what is the angle at which the ball is kicked?

• 50°

• 40°

• 30°

• 20°

What is the initial speed of the ball in the second problem?

• 30 m/s

• 45 m/s

• 35 m/s

• 40 m/s

What is the height of the building in the third problem?

• 300 m

• 200 m

• 350 m

• 250 m

What is the launch angle of the ball in the third problem?

• 35°

• 45°

• 30°

• 40°

How long does it take for the ball to hit the ground in the third problem?

• 13.5 seconds

• 12.5 seconds

• 11.5 seconds

• 10.5 seconds

What is the final speed of the ball before it hits the ground in the last problem?

• 85.5 m/s

• 94.5 m/s

• 88.5 m/s

• 91.5 m/s

What is the direction of the final velocity of the ball in the last problem?

• 75.3° below the x-axis

• 65.3° above the x-axis

• 75.3° above the x-axis

• 65.3° below the x-axis
