A block is sitting on a rough ramp. It is found that a force of F = 200.0 N (directed up the ramp) is required to keep the box from sliding back down the ramp. The angle 𝜃 is 35.0o and the mass of the box is 150.0 kg. What is the coefficient of static friction between...

Starting from rest at t = 0 s, a wheel undergoes a constant angular acceleration. When t = 1.6 s, the angular velocity of the wheel is 5.5 rad/s. The acceleration continues until t = 17 s, when the acceleration abruptly changes to 0 rad/s2. Through what angle does the wheel ...

Finding the slope and y-intercept for x = -9, I beleive is (-9, 0) and the slope is undefined. However what if you are looking for the slope and y-intercept of y = x? Hmmm. It is a vertical line, so you are right, slope is undefined. Now y=x is easy Rewrite it as y= 1*x + 0 ...
