1. ________________ A 100 gram box of Harmony soap is 9.0 centimeters long, 7.0 centimeters wide, and 3.0 centimeters high. What is the volume of the bar of soap in cubic centimeters?
2. ________________ A 100 gram box of Harmony soap is 9.0 centimeters long, 7.0 centimeters wide, and 3.0 centimeters high. What is the density of the bar of soap in grams per cubic centimeter?
3. ___________________ A ball travels eight meters in 5.5 seconds. What is the speed of the ball in meters per second?
4. ___________________ A ball falls a distance d of eight meters in a time t of 1.28 seconds. Given that $\text{d}=\frac{1}{2}g{t}^{2}$, What is the acceleration of gravity g in meters per second2
5. ________________ On a Tuesday evening in February I ran for 58 minutes covering 8.33 kilometers. What was my speed in meters per second?
6. ____________________ A 5.0 gram marble covers 30.0 cm in 0.6 seconds. What is the speed of the marble?
7. ____________________ A 5.0 gram marble covers 30.0 cm in 0.6 seconds. What is the linear momentum of the marble?
Note: Momentum is mass × velocity
8. ____________________ A 5.0 gram marble covers 30.0 cm in 0.6 seconds. What is the kinetic energy of the marble?
Note: $\text{KE}=\frac{1}{2}m{v}^{2}$

1. ___________________ The above graph shows the path of a ball being thrown as was done on Wednesday, 30 January. What is the name of the shape of the path of the ball?
2. ___________________ What causes the ball to fall back towards the ground?
3. k = _________ r = __________

Given the projectile path above in the image on the previous page and the equation:
$y=\frac{-k{x}^{2}}{{r}^{2}}+k$
determine the values of k (the y-intercept) and r ( the distance from the axis of symmetry to the x-intercepts).
4. ___________________What will be the temperature of a mix of melting ice and water?
5. A student examined and tested aluminum, brass, carbon, copper, glass, iron, lead, and zinc. For each the student determined whether the element was a metal or non-metal. The student also determined whether the element was conductor or non-conductor of heat. The student took no numerical measures. What is the most appropriate data representation for this data?
