PRE-LAB 3: Acceleration and Force 1. (3pts) In Part 1, you will repeat your Lab 2 Speeding Up experiment with a focus on forces. . Draw a free-body diagram of the forces acting a. on the cart. otes Draw a free-body diagram of the forces acting on the mass. b. Which forces in the two diagrams are equal? c. oipol 3. (4 pts) We will be using the same cart and motion sensor setup we used in last lab: Force...
Problems 1. FORCE QUESTIONS Answer these three conceptual questions with words, pictures, and if needed equations/math ideas. a)Consider a passenger plane, such as a Boeing 777. Draw a conceptually correct free-body diagram for such a plane when it is flying in a straight line at constant speed and when it is taking off and it is accelerating upwards and forwards. b) We observe that all dropped objects accelerate at a constant rate of about 9.8 m/s near the surface of...
Word Problems You must show all of your work to get full credit. Write as neatly and organized as possible. Put a circle around your final answer. 1.) (10) A cylindrical pulley of mass M 20.0 kg has an inner shaft of radius r 40.0 cm while the outer radius is R 1.00 m, The inner part is attached to the ceiling by a light string and to balance the system the outer part is attached to a mass m...
For the following problem, show all work. Circle your answers. A box of mass m = 5.0 kg is sitting on a ramp, which is elevated at an angle 0 = 20°, compressing a spring Ar = 0.5 m. The spring is released, causing the box to slide up the ramp. At some point, the spring becomes detached from the box. The total length of the ramp is L = 4.0 m and it has a coefficient of kinetic friction...
PHY 221-Test 4 Problems: Show your work (diagrams, equations, mathematical manipulations, numerical substitutions, etc.) for all problems to receive credit (no work- no credit). Place a box around your final answer. Include units with all mumerical answers and record answers with the appropriate number of significant figures. All units must be in standard SI units. Include friction and/or air resistance only where indicated. 15) A grindstone has a moment of inertia of 1.6 x 103 kg-m2. When a constant torque...
2: Problems. Show your work neatly and in detail. List any equations with mich you start or continue calculations. (70 points) Problem 1. Starting with Fc mac mv?lr, F Gmim2/r2 and vr 2TTr/T derive an equation for the period of the orbit of a satellite around the Earth. (10 points)
please explain neatly and show formulas thank you
Question 1 Your answer is partially correct. Try again. The figure shows a thin rod, of length L = 1.50 m and negligible mass, that can p ot about one end to rotate in a vertical circle. A ea ball of mass m 15. C s attached to the other end. The rod is pulled aside to angle eo = 6.80° and released with initial velocity v 0-0. As the ball descends...
Now, back to Earth, where there is gravity. A 1 kg book sits on a frictionless inclined plane, tilted at an angle of 30◦ above the horizontal. Hint: If you have trouble with this problem, look at the force diagram you drew for the last problem and rotate it by thirty degrees. (a) Draw a force diagram for the book. (b) What are the components of the gravitational force parallel to and perpendicular to the ramp? Draw a right triangle...
Part 2: Solving Problem (show all your works and calculation, and write the formula that you choose from formula sheet and find your answer for solving each problem) 1- A 12 kg box is being pulled up an incline by a rope with force 120 N and moves up. The floor is rough and has angle of 200 related to horizontal level. Determine (a) normal force? (b) friction force (c) and acceleration of box? (10 points) coefficient of kinetic friction...
MULTIPLE CHOICE, Show your work in the space provided. Circle the correct answer 1. A person's heart beats 70 times a minute. Calculate the frequency? 2. Estimate the length of your leg (from foot to hip) in meters. Calculate your maximum walking speed? Assume acceleration due to gravity on earth to be 9.8 m/s. If you are vacationing on moon, where the acceleration due to gravity is 1/6 of that on earth, how fast can you walk? 3. A car...
