A 1-kg block is held at rest on a 37-degree incline that has a coefficient of static friction = 0.60 and a coefficient of kinetic friction = 0.50; the block is then released. a) Draw labeled FBD of the block after it is released
b) Determine if the block will slide
c) If it slides, determine its acceleration
d) How long will it take to slide 1.0 meters?
e) How fast will it be going at 1.0 m?

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.

Whithin which type of system is neither the total mass nor the total energy conserved ? a. open b. connected c. isolated d. closed
