Final answer:
To work out VC (b) using the high-low method, identify the knowns (such as v and u'), the unknown (u), and use the appropriate physics equation to solve for the unknown. The specific formula will depend on the context, which might be related to motion, velocity, and time.
Step-by-step explanation:
To work out VC (b) using the high-low method, you'll need to follow these steps:
- Identify the knowns. For example, if v = 0.500c; u' = -0.750c, these are your known velocities.
- Identify the unknown, which in this case is u, the initial velocity.
- Choose the appropriate equation that will allow you to solve for the unknown. This equation must incorporate the knowns and the variable you are trying to solve for. The specific equation would depend on the context, which could be a physics formula relating to motion, velocity, and time.
For instance, if "y" represents some aspect of motion and the known is y = 30.00, and you need to find v in terms of c, you would start with an equation that expresses y in terms of v and c.
If the context is about projectile motion, and you're solving for the time to the highest point, the typical approach is to use the kinematic equation y = Yo + (Voy + Vy)t. Since yo is zero, the equation simplifies accordingly to solve for the variable of interest.
