Answer the following problems on a separate sheet of paper. Use the proper procedure for solving problems. Watch for units and significant digits. Show all work!

1. When we last left our super heroes the evil Mahlum-in-ator was feeling a little crappy. While he was diabolically plotting his next evil task to destroy Super-Anderson he picked up a poop ball and flung it from the back of the truck. The ball of poop landed at the top of a hill where it started from rest and then rolled down the incline at a constant rate of acceleration of 2.00 m/s/s East. What was the velocity of the poop after 8.5 seconds?

2. How far does the poop ball in problem #1 roll in 10.0 seconds?

3. The truck that Mahlum-in-ator was riding in was traveling at 88 km/hr 22° North of West when the Mahlum-in-ator stated “eureka”. It was at that moment he realized the super-Andersons weakness lies within the pink fuzzy slippers she constantly wears. It is from those slippers that she recharges her super powers. He taps on the glass of the truck and the truck decelerates at a constant of 8.0 m/s/s. How long does it take for the truck to come to a stop?

4. How far does the truck in problem #3 move after the breaks are applied?

5. The Mahlum-in-ator in an effort to return to the super cave, starts from rest and moves with a constant acceleration for a displacement of 150 m South in 5.0 seconds. What was the acceleration of the Mahlum-in-ator?

6. Realizing that the super cave is very hard to find the evil Mahlum-in-ator calls for the help of his faithful followers, the accelerated science drones! He calls for them by taking his MOLE/chemistry cd and playing it at top volume. The drones hearing the call of their leader start marching towards the sound. All of the drones get into the evil science MOLEbile that is programmed to find the source of the mole music. The car accelerates uniformly from 16 m/s west to 32 m/s west in a time of 10.0 seconds. What is the MOLEbile acceleration?

7. How far did the MOLEbile move while accelerating?

8. With all of the drones looking for the entrance to the super cave it was easily found. They quickly set up a trap to capture the pink fuzzy slippers of recharging super powers from the one known as super-Anderson. Using the same speaker system that called the evil drones to the Mahlum-in-ators side, the drones inserted a cd of the greatest band of all time METALLICA!!! Hearing the greatest music of all time super-Anderson leaves the super cave to find the source of the wonderful sound. She was then ambushed by the drones throwing “HEAVY METAL” balls down from atop the cave. Each ball took 6.3 second to reach the top of Super-Anderson’s head. How high was the top of the cave?

9. Sensing that Super-Andersons defeat was near the evil Mahlum-in-ator used his super powers of antigravity to lift a house from a nearby village and drop it on the head of super-Anderson. The house was 25.0 m above super-Anderson’s head. How fast was the house going when it hit Super-Anderson’s head?

10. How much time did Super-Anderson have to move out of the way of the falling house?

11. The house landed directly on top of Super-Anderson leaving only her feet sticking out from under it. The drones started to sing in unison “ding dong S-A, is dead S-A is dead, S-A is dead, ding dong Super-Anderson is dead” The Mahlum-in-ator walked up and removed the pink fuzzy slippers from her feet, the stench from her feet knocked the Mahlum-in-ator out cold. His drones rushed to his side placed him and the slippers into a sled pushed him down a hill. The sled accelerated at 1.4 m/s/s East. If he started from rest how far does he travel before reaching a maximum velocity of 7.00 m/s East? (At this rate of speed the cold air will drive the stench from his nostrils and clothing)

12. Thinking that they have pulled off the most evil diabolical plot ever the Mahlum-in-ator and drones celebrate by listening to lectures at the science bag presentation on the UW-Milwaukee campus. Meanwhile back at the scene of the house drop, a car passing by happens to be playing a Dixie chicks song on the radio. The almost dead Super-Anderson hears the music and starts to regain her strength. She emerges from under the house and gets into her invisible jet. The invisible jet starts from rest, and undergoes and acceleration of 1.6 m/s/s East for a displacement of 1600 m East before it takes off. What is the velocity of the plane just before take off?

13. What is the time required for takeoff of the plane?
