I think I got it; the numbers make sense and the chart looks good. I think my problem was that I forgot how to use the slope in the quadratic equation.
Thanks for the help, I really appreciate it...
sorry, x0 is suppose to be v0... I just corrected it...
And yes, Y is the height above the ground. The initial y position was 1.20 m. After the projectile was fired, we used a platform to stop the ball at ya = 0.4 m, and yb = 0.1 m. Using experimental data and projectile motion equations I...
The experiment was to measure muzzle velocity of a ball fired by a 'spring gun'. Then to use the equations of projectile motion in order to determine the projectile trajectory. During the experiment we used a variable-height platform to stop the ball mid-air (at y = 0.4 m & y = 0.1 m). Now we're...
thanks for the feedback, this is my rationale for setting up the problem the way I did:
V1M1 = V2M2
(.00500 * 12.0 M HCl) = (.600 M * V2)
divide both sides by .600 M
V2 = (.00500 * 12. M HCl)/(.600 M)
V2 = 100. mL
And if it's not too much can you check this one too:1. How many mL of water must be added to 5.00 mL of 12.0 M HCl to prepare a hydrochloric acid solution that is 0.600 M? Assume that the volumes are additive.My solution:
(.00500 L * 12.0 M HCl)/(0.600 M) = .1 L = 100. mL
Stoichiometry... Did I work this problem correctly?
1. We dissolve 3.778 grams of a sample that contains some sodium oxalate, Na[SIZE="1"]2C[SIZE="1"]2O[SIZE="1"]4, in water and acidify the solution with excess sulfuric acid. The sample requires 18.74 mL of 0.08395 M KMnO[SIZE="1"]4, potassium...
Question:
The mass of a container filled with liquid mercury is 244.0 g, and the mass of the empty container is 110.2 g
a. What is the volume of the container? (density of mercury = 13.546 g/ml)
b. The same container is filled with a second liquid, and the mass of the filled container...
