Instructions: 1. Draw the schematic of the situation described in the wording of the problem. This schematic includes a list of the data given in the wording of the problem, such as initial position (x, yo), initial velocity Ivo, V, Vol, final position (x,y), final velocity (V, V, W) or maximum height (ym). Make a decision on whether you want to use "y" or "h" for the vertical axis and keep it consistent throughout all the problems. Write down the...

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...

8) The diagram above shows a 2 kg cart that is set on top of a table. It is able to roll with very little friction. The cart is attached to a 7 kg weight by a light thread that frictionlessly slides over a pulley. How much horizontal force must you apply to the cart in order to keep the system from beginning to move? Correct,...

35. In Chapter 1 acceleration is defined as a = ∆v. Show ∆t that on an inclined plane, the acceleration of a cart that gains 6.0 m/s each 1.2 s is 5.0 m/s2. 36. In this chapter we learn that the cause of acceleration is given by Newton’s second law: a = Fnet/m . Show that the acceleration in Problem 35 results from a net force of 15 N exerted on a 3.0-kg cart. (Note: The unit N/kg is equivalent...
