Nerd-A-Pult using Unit Vectors

What is the main concept introduced in the first section of the video?

• Finding the angle of projection

• Determining time of flight

• Calculating acceleration

• Using unit vectors to solve problems

What is the initial position of the ball in terms of unit vectors?

• 1.54 I + 2.86 J

• 9.81 I + 0 J

• 0.93 I + Y J

• 0 I + 0 J

How is the initial velocity of the ball expressed in unit vectors?

• As a matrix

• As a scalar value

• As a single vector

• As separate X and Y components

What is the X component of the initial velocity?

• Initial velocity times sine Theta

• Initial velocity divided by time

• Initial velocity times cosine Theta

• Initial velocity minus acceleration

What is the acceleration of the ball in the Y direction?

• 4.905 m/s²

• -9.81 m/s²

• 9.81 m/s²

• 0 m/s²

What equation is used to find the final position of the ball?

• Final position = Initial position + Initial velocity * time + 1/2 * acceleration * time²

• Final position = Initial position + 1/2 * acceleration * time²

• Final position = Initial velocity * time + 1/2 * acceleration * time²

• Final position = Initial position + Initial velocity * time

Where should the basket be placed for the ball to land in it?

• 6.0 cm above the original height

• At the same height as the original

• 6.0 cm below the original height

• 9.81 cm below the original height
