Choose the one alternative that best completes the statement or answers the question. 1) A spring with a spring constant of 400 N/m is compressed 2 cms. How much energy does it store? A) 0.02 J B) 0.42 J C) 5.60 J D) 0.08 J E) 1.22 J 2) A 20-N crate starting at rest slides down a rough 5.0-m long ramp, inclined at 25 o with the horizontal. 20 J of energy is lost to friction. What will be the velocity of the crate at the bottom of the incline? Figure 1 3) In Figure 1, A 9.0-kg hanging weight (B) is connected by a string over a pulley to a 5.0-kg block (A) sliding on a flat table.
