Relative velocity example 1

The video tutorial explains how to find the velocity of car A relative to car B. It introduces the problem, describes the relative velocity formula, and breaks down the components of each car's velocity. Using trigonometry, the tutorial calculates the velocity of car B and rearranges the formula to solve for the relative velocity of car A. The solution is explained with both mathematical steps and intuitive reasoning.

What is the initial velocity of car A?

• 10 meters per second to the left

• 10 meters per second to the right

• 5 meters per second to the right

• 5 meters per second to the left

Which formula is used to find the velocity of A relative to B?

• Velocity of A relative to B = Velocity of A + Velocity of B

• Velocity of A relative to B = Velocity of A - Velocity of B

• Velocity of A = Velocity of B + Velocity of A relative to B

• Velocity of A = Velocity of B - Velocity of A relative to B

How is the horizontal component of car B's velocity calculated?

• 10 cosine 60

• 10 sine 60

• 5 cosine 60

• 5 sine 60

What is the final relative velocity of car A with respect to car B?

• 10 meters per second

• 0 meters per second

• 8.66 meters per second

• 5 meters per second

Why does car A appear stationary to car B in the horizontal direction?

• Car A is moving in the opposite direction to car B

• Car B is moving faster than car A

• Car A and car B have the same horizontal velocity

• Car A is moving faster than car B
