Learn how to solve a word problem using square roots, velocity and distance

The video tutorial explains how to use the formula v^2 = 64H to find the velocity of a falling object. It begins by identifying the variables V (velocity) and H (distance fallen) and demonstrates solving for velocity after a 10-foot fall. The tutorial then explores how the velocity increases when the object falls 20 feet, emphasizing the importance of understanding and applying the formula correctly.

What does the variable 'V' represent in the formula v^2 = 64H?

• Time taken to fall

• Velocity in feet per second

• Mass of the object

• Height of the object

If an object falls 10 feet, what is the value of v^2 using the formula v^2 = 64H?

• 320

• 128

• 64

• 640

What is the velocity of an object after falling 10 feet?

• ±80

• ±90

• ±64

• ±100

How do you calculate the velocity increase when the object falls 20 feet instead of 10 feet?

• Divide the final velocity by the initial velocity

• Multiply the initial velocity by 2

• Subtract the initial velocity from the final velocity

• Add the initial and final velocities

What is the velocity of an object after falling 20 feet?

• 30.50

• 45.67

• 25.30

• 35.77

What is the increase in velocity when the object falls from 10 feet to 20 feet?

• 10.48

• 15.50

• 12.34

• 8.90

How do you find the increase in velocity between two points?

• Divide the velocity at the second point by the velocity at the first point

• Multiply the velocities at both points

• Subtract the velocity at the first point from the velocity at the second point

• Add the velocities at both points
