Use this formula to show that theacceleration of a cart on an inclined plane that gains 6.0 m/s each 1.2 s is 5.0 mn/s².38. In this chapter, we learned that the cause of acceleration is given by Newton's second law:a = Fnetm. Show that the 5.0-m/s? acceleration in Exercise 37 can result when a 15-N netforce is exerted on a 3.0-kg cart. (Note: The unit N/kg is equivalent to m/s².)41.

30. A mass m falls under gravity (force mg) through a liquid whose viscosity is decreasing so that the retarding force is -2mv/(1+t), where v is the speed of m. If the mass starts from rest, find its speed, its acceleration, and how far it has fallen (in terms of g) when t = 1.
Oak (720 kg/m3), Water (1000 kg/m3) (0.72 g/cm3; 1 g/cm3) Calculate the fraction of the object (oak) above the surface of the fluid (water). State if the object floats or sinks.
Lurking alligators. An alligator waits for prey by floating with only the top of its head exposed, so that the prey cannot easily see it. One way it can adjust the extent of sinking is by controlling the size of its lungs. Another way may be by swallowing stones (gastrolithes) that then reside in the stomach. The figure shows a highly simplified model (a "rhombohedron gater") of mass 125 kg that roams with its head partially exposed.The top head surface has area 0.180 m2. If the alligator were to swallow stones with a total mass of 1.8% of its body mass (a typical amount), how far (in mm) would it sink? Number i Units
