Q1. A sled is pushed by 12 monkeys with a constant force until it reaches a velocity of 18.9 m/s. All 12 monkeys stop pushing and the sled slides across a rough surface. From time monkeys stop pushing the box slides 12.3 meters before it comes to a stop. If the u of k of the contact is 0.21, what is the mass of the sled?

Q2. While Voyager 2 sent back pictures of Neptune during its historic flyby of that planet in 1989, the spacecraft's radio signals travelled for 4 hours at the speed of light to reach Earth. How far away was the spacecraft? Give the answer in kilometres, using powers-of-ten notation.

Q3. A butterfly at eye level is 27 cm in front of a plane mirror. You are at the back the butterfly, 88 cm from the mirror. What is the distance between your eye and image of the butterfly in the mirror?
