   * **Question:**How much power does the mechanism need to operate successfully?
-  * **Expected Answer:** $t=d/v$
+  * **Expected Answer:**
-                         $t=(h)sin(θ)/(v)$
+$$t=d/v$$
-                         $P = W_{motor}/t (watts)$
+$$t=(h)sin(θ)/(v)$$
+$$P = W_{motor}/t (watts)$$
+  * **Question:** How would you change your system to use energy to solve this problem?
+  * **Expected Answer:**
+$$Work -> System: Tube$$
+$$Energy -> System: Earth+Tube+Motor$$
+  * **Question:** Explain how you determined the sign of each component doing work on your system.
+  * **Expected Answer:**
+  * $W>0$ if force acts in same direction of displacement $(W_{motor})$
+  * $W<0$ if force acts in opposite direction of displacement $(W_{grav}$ & $W_{friction})$
+  * **Question:** How would the work done by gravity change when the tuber slides down the hill if you increased or decreased the angle of the hill?
+  * **Expected Answer:** It doesn't change because the height of the hill remains the same so the work done by gravity remains the same. $(K=W_{surr})$

+Once you are the top of hill, Joe wants the fun to begin. In order to keep up with the competition, the tubing hill needs to be exciting. There is a ramp at the bottom of the hill where the tubers will be launched through the air. A 5m diameter flaming hoop is located 15m from the ramp and 10m off the ground. Ensure the tubers complete this stunt through the hoop safely. Totally rad dude!!
