Two masses attract each other with the force of 1N. If the first mass is tripled, another mass is quadrupled and the distance between masses is doubled what is the new attraction force. 12.
Which of the following would count as a centripetal force? (Choose All That Apply) The force of gravity causing the earth to travel in a circular path around the sun The tension in a rope as you swing a yo-yo in a circle over your head The force of friction from the seat on you as you travel around a curve while driving a car The normal force acting on a car as it drives in a circle All of...
Conservation of Momentum PHY 121 Lab 10 7) Now seeing what you saw, were you right? What can you say about the momentum before the collision and the momentum after the collision? Final Total Kinetic Energy after the collision: nǐ--%Error_07__ Now change the red cart to being heavier than the blue cart and the blue cart is again initially stationary (0m/s) Initial momentum: 10 N Initial Kinetic Energy: 25 J 8.) Write what you expect to happen to the carts...
2. If your coefficient (1) were 0.45 and the Normal Force were 400 N, what would be the Friction force?
Part A--> what magnitude of force must you apply to
hold the platform in this position?
Part B--> how much additional work must you do to move the
platform 0.180 meters further?
Part C--> what maximum Force must you apply to move the platform
to the position in Part B?
As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff ideal springs arranged side by side so...

(d) If you were to naively apply Newton's second law to this situation, what is the magnitude of the apparent centrifugal force acting on the child? N8M.5 An elevator is accelerating upward at 1.8 m/s. Someone is standing on a bathroom scale in the elevator, and it reads 180 lb. Use equation N8.12 to calculate the per- son's true weight. N8M.6 A test tube is placed in a centrifuge. When the cen- trifuge rotates at full speed, the test...
Impulse-Momentum theorem. For a given amount of momentum change, clearly describe a situation where you would want to have the time interval extended to minimize the acting force and where you would want the time interval shortened to maximize the acting force.
If you worked in a hospital and were asked to determine 15 activities to apply activity based costing what would they be? Go to at least two discussions from your classmates and comment by post a thread on three of their activities which you did not mention in your thread. on

How would you calculate the area under a force/change in length graph? What would be the units? Choose 4 of the choices below J F*x 1/2 F*x Nm N/m F/x spring constant kgm2/s2
What is the physics definition of a "force"? A (change in momentum)/(change in time) B physical power or strength possessed by a living being C might, as of a ruler or realm D (change in time)/(change in momentum)
