The coefficient of static friction between the block and the inclined plane is 0.4 and 0=25º. The block is placed on the inclined plane. The block will:

A not move

B. start moving down the incline and then stop before it reaches the bottom of the incline

C. start moving down the incline and continue to increase its velocity

D. start moving and increase its acceleration until it reaches the bottom of the incline

E. start moving and then its acceleration will decrease

F

3 kg

5 kg

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

heat the gas and measure the pressure
