How do engineers use the quadratic formula?
In problems of motion, especially involving constant acceleration, a quadratic equation will from the formulas of motion to solve for time, usually. This is just one example.
How does a graph slowing speed differ from a graph showing acceleration?
Yes. One shows speed and the other shows acceleration. The variables are usually plotted against time but that need not be the case. They could be plotted against displacement, for example.
How much is the acceleration of a baseball thrown if the ball goes from 0 to 90 mph in a one-second time period?
Acceleration is change of speed / time, so in this case you have 90 miles per hour per second. While this is a valid unit of acceleration (a unit of distance divided by two time units), you may want to convert this to other units. Reminder: 1 hour = 3600 second; and 1 mile = 5280 feet.
How do you find acceleration given mass and distance?
Not enough information. One equation you can often use is Newton's Second Law: force = mass x acceleration Which, when solved for acceleration, gives you: acceleration = force / mass
How do you solve a formula?
If you just want to solve it put the numbers in instead of the letters and you will get an answer but if you want to rearrange the formula or solve the equation then follow these simple steps 1) get rid of fractions by timesing by the fraction 2) move all of the x's (if you want x to be the subject) to the same side 3) if you cannot get rid of the other values on one side by taking them away( subtraction) or dividing them away then take a factor of x
