We then drew a force diagram for the force acting on the barbell and when the lifter held the barbell over his head. Were: B= the angle=35 degrees Fn= The normal force m= mass g=gravity F= the force exerted by each arm We then used the following equation W = mg to calculate the weight of the barbell. Were: W= weight m=mass g=gravity W = 135kg ∙ 9.81m/s2 = 1324.35 N We then estimate the angle of each arm acting on the bar to be about 60 degrees. We then broke down both Vector F into its component vectors

was to provide us with a chance to practice the statistics experimental design‚ through measuring how far the gummy bears fly from a catapult in centimeters. This catapult contains 3 different stages from which to launch gummy bears at different angles: front‚ middle‚ and back‚ as well as two different positions upon the catapult at either the front or back. Then‚ based upon each configuration‚ we launched the gummy bears 5 times‚ for a total of 2x3x5‚ 30 treatments. Controls For this‚ there

influenced oscillation were the length of the string in meters‚ the angle that the sphere was released on‚ and the mass of the sphere. The factors with the greatest influence on the oscillation was the length of the string based on the data we recorded. The data showed an increase in the average time period of oscillation as the length of the string increased. The factors that had the least influence were the mass of the sphere and the angle at which it was released since the average periods were extremely

The Unit Circle • Using your medium of choice (no garbage cans‚ food or glitter‚ please)‚ create a display of the Unit Circle. • Your display should include all the angles represented on the unit circle. • Angles should be labeled in degrees and radians. Please be sure to measure the angles with a protractor to ensure accurate representation. • This project is a quiz grade! • Be creative and have fun! • Fewer points may be given if your object is already a

SOLUTION: The trapezoid ABCD is an isosceles trapezoid. So‚ each pair of base angles is congruent. Therefore‚ ANSWER: 101 2. WT‚ if ZX = 20 and TY = 15 SOLUTION: The trapezoid WXYZ is an isosceles trapezoid. So‚ the diagonals are congruent. Therefore‚ WY = ZX.

instrument used for measuring horizontal and vertical angles. A basic theodolite usually consists of a small sized telescope linked with mechanisms to measure horizontal and vertical angles. It has several moving parts and is quite heavy. The theodolite telescope is fixed within perpendicular axes- the vertical axis and the horizontal‚ or trunion‚ axis. The instrument is fixed on a base that can be rotated on a tripod by a leveling system. The angle to the desired point can be measured by pointing the
