Case 3 m1 = _______ x1 = 10 cm m2 = 200 g x2 =_________

A sign has a mass of 1050 kg, a height h = 1 m, and a width W = 4 m. It is held by a light rod of length 5 m that is perpendicular to a rough wall. A guy wire at 23° to the horizontal holds the sign to the wall. Note that the distance from the left edge of the sign to the wall is 1 m.

(1.5 pts) Find Maximum Takeoff Weight for the given conditions. Assume takeoff is at Max Recommended Takeoff weight accounting for Density altitude (see Figure 11-21).

Plot (draw) the kinetic energy of the 300 kg mass as a function of position from point A until point D. [Show all work, use proper scale, show equations and substitution with units and show all points on the graph].

In our data, the least mass of 10 grams had an acceleration of -6.456 m/s2, followed by 50 grams with an acceleration of -9.133 m/s2, followed by 100 grams with an acceleration of -9.414 m/s2, lastly 200 grams had an acceleration of -9.614 m/s2. The group data did not have outliers in the average velocity values which were used to find the acceleration.

A known mass was compared with an unknown mass with the use of the balance principle. With the meter stick on the support stand the unknown mass (m1) was suspended near one end of the meter stick while the other stick was suspended with m2. Until the meter stick was in balance its position was adjusted. The unknown mass was then removed in which the actual mass was then determined by using a laboratory balance.

Distance to Accelerate and Stop with a Single Engine Failure at V1 = 5500 fts

Repeat this step by adding one bar to the cart. Each bar is 500 g. The total mass of the cart is now 1000g.

For the purpose of this problem use 10 m/s 2 for g and 100000 N/m2 for 1 atm.

We will determine the acceleration of the weights of an Atwood’s Machine, both experimentally and theoretically. We will attempt to verify Newton’s Second law which is a mathematical statement relating force, mass, and acceleration.  Newton’s Second law states that acceleration, a, is directly related to net force, F, and inversely related to mass, m. Naturally this give F=ma.  Using the Atwood’s Machine experimental acceleration data (for 10 different runs with 10 different combinations of masses) will be gathered and compared to the theoretical acceleration which is predicted by Newton’s Second Law using a modified version of  F=ma. The only two variables in this system system that we will control are the the two masses. We

where F is the gravitational force, M and m are masses, and r is a length. Force has the SI units kg ∙ m/s2. What are the SI units of the proportionality constant G?

Question 4: Ali lets go of the legs of a 543g double pendulum with a radius of 0.1 m from a height of 0.3m and the velocity is 8 m/s. Calculate the centripetal acceleration and gravitational potential energy. (Knowledge)
