It mentions about rearranging the equation but I don't think it shows you. Do you know what it would look like if it was rearranged? If so please show me.Bandersnatch said:Hi, Jacob. Can you rearrange the equation so that it has just t on one side?

Wouldn't you just 0.5 * 9.81 + 0 = 4.905t2. Then that would give you 40 = 4.905t2Bandersnatch said:The forum rules prohibit us from giving you the answer. You have to show your work.
If you're working from this textbook, you should already know how to rearrange algebraic equations.
The equation is
$$40=0+\frac{1}{2}9.8*t^2$$
How would you move all the numerical values to the left?
But that still doesn't make sense because when you divide afterwards it still doesn't give you the answer.Jacob T Anderson said:Wouldn't you just 0.5 * 9.81 + 0 = 4.905t2. Then that would give you 40 = 4.905t2
This is not algebraically correct.Jacob T Anderson said:Wouldn't you just 0.5 * 9.81 + 0 = 4.905t2. Then that would give you 40 = 4.905t2
Show your work.Jacob T Anderson said:I tried dividing both sides by 4.905 and get t = 8.15
Simpler than that. Take the square root of both sides.Jacob T Anderson said:I got it! I forgot about the Quadratic Formula
The first step in solving a worked problem is to carefully read and understand the problem. This includes identifying the given information, what is being asked, and any relevant equations or concepts.
It is important to clearly label and organize your work when solving a problem. This includes writing down all given information, identifying known and unknown variables, and showing all steps of your calculations. It can also be helpful to draw diagrams or use tables to visually represent the problem.
Choosing the appropriate formula or method to use in solving a problem depends on the given information and what is being asked. It is important to understand the concepts and equations related to the problem and select the most relevant one.
If you are stuck on a step or cannot get the correct answer, it is important to double check your work and make sure all calculations are correct. You can also try approaching the problem from a different angle or seeking help from a teacher or classmate.
To determine if your answer is reasonable and makes sense, you can check the units of your final answer to make sure they are in the correct form. You can also estimate the answer to see if it is in the same range as your calculated answer. Additionally, you can use common sense and logic to determine if the answer aligns with the given information and the context of the problem.
