Centripetal Force Lab Activity Analysis: 1. A) Average Percent Difference: 50g: (values expressed in newtons) Step 1: Calculate the average value of the two variables Average Value= Value 1+ Value 2 /2 = 0.49+ 0.61/2 = 1.1/2 = 0.55 Step 2: Calculate the difference between the two variables Difference= Value 2- Value 1 = Fc- Fg = 0.61- 0.49 = 0.12 Step 3: Calculate % difference % difference= difference

Assignment – Physics 1 1. Two carts‚ one twice the mass of the other‚ experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact

Earth then it is around 8km/s. 17. Why is it important that such a satellite be above Earth’s atmosphere? It is important because it avoids the heating effects of atmospheric friction. 18. What force acts on a satellite that is above Earth’s atmosphere? The only force is gravity. Plug and Chug 1-5 1. Calculate the resultant velocity of an airplane that normally flies at 200 km/h if it encounters a 50 km/h tailwind. If it encounters a 50 km/h headwind? 200+50=250km/h 200-50=150km/h 2

CE 270 - Final Exam Problem No. 1. (20 points) A rectangular cross-section that is 50 mm wide and 250 mm deep is subjected to shear force of 22 kN‚ axial force (tension) of 16.5 kN and bending moment of 33 kN-m. Calculate and show the stress diagrams in the cross-section. What is the maximum normal stress‚ and where does it occur. What is the maximum shear stress and where does it occur. Problem No. 2 (20 points) Determine the principal stress‚ the maximum in-plane shear stress

In this movie batman leaps from a building for 4 to 5 seconds before opening his wings neglecting significant air resistance (this affect Newton’s 3rd law). Scientists found out that all that force applied exert about 1600 pounds of force to his arms. Not even the worlds strongest man can lift that much!! Next we talk about spider-man and his trickery. In his the movie spider-man 3 is basically

Work with friends on them‚ explain your solutions and convince yourselves that you understand the problems. I can’t tell you if you are right - I just don’t know! 1.

Force is required to produce motion in a body. Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real

In this investigation three different variables were tested to determine their effect on the force of friction. All throughout the lab it was important to record the data found to identify how much the three variables affected the force of friction. The purpose of the first part of the lab‚ 4.1 What a Drag!‚ was to measure the force required to pull a block over five different surfaces. The sliding surfaces used in the lab were the tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sandpaper
