Q1. Megan's mass is 27 kg. She climbs the 4.8 m ladder of a slide and reaches a velocity of 3.6 m/s at the bottom of the slide. How much work was completed by friction on Megan? Imagine that air resistance is negligible.

Q2. One rod is made from lead and another from quartz. The rods are heated and experience the same change in temperature. The change in length of each rod is the same. If the initial length of the lead rod is 0.090 m, what is the initial length of the quartz rod? (The coefficients of linear expansion for quartz and lead are αQ = 5.00 10-7 (C°)-1 and αL = 2.90 10-5 (C°)-1, correspondingly.)
