How much force will be required to push this mass to the top of the incline at a constant speed?

Below are the answers for the bellwork. I should have this graded by Monday. An automobile, which has a mass of kg, is moving with a velocity of The tires on the car have a diameter of 78 cm. Mechanics often us cheater bars to loosen stubborn bolts.

Answers to the following: A cart, which has a mass of 2.

What will be the total clockwise torque acting on this system? We don’t have enough time for a unit test on momentum, so instead your final will consist of multiple choice problems from the whole semester and free response problems only from the momentum unit. Monday, November 16, Lab: What will be the rate of acceleration of your car?


A meterstick is pivoted at one end by a nail inserted through the 2. What will be the total energy of this ball as it is thrown from the top of the building? What is the change of momentum due to a force that is not constant? What will be the kinetic energy of the cart when it reaches the bottom of the incline? I could not toruqes my videos to embed in my Powerpoint – sorry!
