The diagram below shows a block of mass m=2.00kgm=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and F3=8.00NF3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...

Consider the mountain known as Mount Wolf, whose surface can be described by the parametrization r(u, v) = u, v, 7565 − 0.02u2 − 0.03v2 with u2 + v2 ≤ 10,000, where distance is measured in meters. The air pressure P(x, y, z) in the neighborhood of Mount Wolf is given by P(x, y, z) = 26e(−7x2 + 4y2 + 2z). Then the composition Q(u, v) = (P ∘ r)(u, v) gives the pressure on the surface of the mountain...

- You find a smooth, spherical crystal ball of radius R = 4 cm, and you wish to determine its index of refraction n. (Note, the crystal ball is transparent, made of a uniform material, and has no bubbles or defects inside.) When the sun is directly overhead, an image of the sun forms on the ground when the ball is a distance ℎ = 2.35 cm above the ground. For your work below, treat the sun as a point...
