Consider two force vectors in the xy-horizontal plane. Suppose a force of 18.7 N pointing along the +x-axis is added to a second force of 20.1 N directed at 55 degrees to the +x-axis , also in the horizontal plane. Find the resultant vector for this sum.
how do you do 7 and 8 ?
ah arbnrary number nents, and all 2-companents separately to f of vector ately to find x-, y"r z-components of the resultant vector. B) Break the (given) vectors down into their x-, y, and 2-componerto c) Combine total x, y-, and z-components using Pythagorean Thetee sine the resultant vector and use tangent to determine its angle. and cosines nd the magnitude of Graphical Representation of Vectors You will need o ruler, graph poper,...
Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....
a. Find the FV of $1,000 invested to earn 10% annually 5 years from now. Answer this question by using a math formula and also by using the Excel function wizard. Inputs: PV = 1000 I/YR = 10% N = 5 Formula: FV = PV(1+I)^N = Wizard (FV): $1,610.51 Note: When you use the wizard and fill in the menu items, the result is the formula you see on the formula line if you click on cell E12. Put the...
ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...
