A 6.30 kg block is pushed 9.00 m up a smooth 36.0° inclined plane by a horizontal force of 74.0 N . If the initial speed of the block is 3.15 m/s up the plane. Required:
a. Calculate the initial kinetic energy of the block.
b. Calculate the work done by the 80.0N force.
c. Calculate the work done by gravity.
d. Calculate the work done by the normal force.
e. Calculate the final kinetic energy of the block.

Zirconium has an hcp crystal structure and a density of 6.51 g/cm3. (a) what is the volume of its unit cell in m3? (b) if the c/a ratio is 1.593, compute the values of c and a.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
