In this situation both objects start combined together. Object one has a mass of 10.0 kg and object two has a mass of 5.0 kg. Combined they are at rest, however they then interact and object one pushes away at 4.0 m/s. What will object two’s velocity be at this point?

5. Consider an object weighing m (kg) that is initially at rest and experiences a constant acceleration of a (m/s2) for a duration of t (s). Express your answer to each of the following questions in the form of an equation involving only the variables m, a, and t (neglecting the effects of friction). (a) What is the force on the object? (b) Integrate the acceleration to obtain the final velocity of the object. (c) Integrate the velocity to obtain...

H. Two objects start moving at the same time. Object A is initially at x x = 8 m and starts moving to the left at constant speed of 2 m/s and object B is initially at x2 m and starts moving to the right at a 1-1-1- constant speed of 3 m/s. Use the coordinate axes on the right to plot the position vs. time for both objects (for at least 4 seconds) then use your plot to identify...

Two objects undergo an elastic collision. Object 1 has a mass of 2.75 kg and object 2 a mass of 2.6 kg. Just prior to the collision, object 1 has a kinetic energy of 51 J and object 2 is at rest. What is the initial velocity of Object 1? What is the total kinetic energy of the two cart system after the collision? What is the total momentum of the two cart system after the collision?
