- What do vectors and scalars have in common? How do they differ?Mountain pull. A large mountain can slightly affect the direction of “down” as determined by a plumb line. Assume that we can model a mountain as a sphere of radius R=2.00 km and density (mass per unit volume) 2.6*103 kg/m3. Assume also that we hang a 0.50 m plumb line at a distance of 3R from the sphere’s center and such that the sphere pulls horizontally on the lower end. How far would the lower end move toward the sphere?VECTOR ADDITION: Find the sum of two ‘forces’: 100 g at 30º and 200 g at 120º, by: A) Graphical Method: Make the X- and Y-axes. Use a scale of 25 g = 1.0 cm. Draw arrows of appropriate lengths at 30º and 120º, both starting from the origin. Add them using the Parallelogram method. Measure the length and angle of the resultant. Convert length to magnitude of the resultant vector using the scale used to draw the vectors. Record the results in the Data Table. B) Analytical Method: Compute the sum of the two vectors by using the Component Method (Ax = A cosθ and Ay = A sinθ ) as well as the Triangle Method (A/Sin α = B / Sin β = C / Sin γ and C2 = A2 + B2 – 2AB Cos γ). Record the results in the Data Table.

- A crate of mass m=48.2 kg is on a horizontal surface. Assume there is no friction between the crate and the surface. Two forces with magnitude F=15.7 N are applied to the crate, as shown. One force is horizontal, and the other makes and angle of φ = 21.2∘ with horizontal, as shown. 1)Write an expression for the magnitude of the acceleration of the crate in terms of F, m , and φ. 2)What is the magnitude of the acceleration of the crate in m/s2?A 100-N force is making an angle of 60° with the horizontal. Find the vertical and horizontal components of the force.Redo Example 5, assuming that there is no upward lift on the plane generated by its wings. Without such lift, the guideline slopes downward due to the weight of the plane. For purposes of significant figures, use 2.91 kg for the mass of the plane, 12.2 m for the length of the guideline, and 18.2 and 36.4 m/s for the speeds. (a) Number (b) Number Units Units

Consider the situation shown where two boxes of mass m and m2 are placed on a plane tilted at angle 0. A spring with a spring constant of k is compressed by the boxes a distance s, and the whole assembly is at rest. Find the friction force of the plane on the lower box and the friction force between the boxes. Do you need to Ms 'me know the coefficient of static friction? If you believe you do it is µ. Present your answer in terms of the symbolic quantities given. Of course, present Free Body Diagrams.A 284N crate resting on a plane inclined 37-degrees with the horizontal requires a 23.9N force to bring it down to 6.4m from its initial position. The force is applied 55-degrees with respect to the horizontal. Neglecting friction between the crate and plane, determine the time (in seconds) that the crate had travelled a distance of 6.4m. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.
