Problems 49 through 52 show a partial motion diagram. For each: a. Complete the motion diagram by adding acceleration vectors. b. Write a physics problem for which this is the correct motion diagram. Be imaginative! Don’t forget to include enough information to make the problem complete and to state clearly what is to be found. c. Draw a pictorial representation for your problem. 49 FIGURE P1.49 50 FIGURE P1.50 51 FIGURE P1.51 52 FIGURE P1.52

1.0 kg block of ice to melt in the kitchen. The temperature in the kitchen is 31 °C. The ice starts out at 0 °C and takes an hour to melt and reach the same temperature as the surrounding room (31 °C). How much heat does the 1.0 kg of ice/water absorb from the room as it melts and heats up to 31 °C in Joules absorbed?
Latent heat of fusion for water/ice is 334,000 J/kg
Specific heat of water is 4186 J/kg°C
5.84 If the coefficient of static friction between a table and a uni-
form, massive rope is μ, what fraction of the rope can hang over the
edge of the table without the rope sliding?
5.97 Block A, with weight Figure P5.97
3w, slides down an inclined plane
S of slope angle 36.9° at a constant
speed while plank B, with weight
w, rests on top of A. The plank
is attached by a cord to the wall
(Fig. P5.97). (a) Draw a diagram
of all the forces acting on block
A. (b) If the coefficient of kinetic
friction is the same between A and
B and between S and A, determine
its value.
