2. Refer to figure 1 of an object's velocity vs. time plot. Calculate your best estimation of the initial acceleration and the distance traveled. Calculate the force the object needed to start moving. 3. A moon's orbital angular velocity and orbital velocity about a planet are 6.28x108 rad/sec and 12.56 m/s respectively. Calculate this moon's distance from the planet and the planet's mass. 4. Water flowing through a tube with a diameter of 10.0 cm has a velocity of 12.5 m/s. The diameter shrinks to only 2.0 cm wide and incurs an increase of density to 1020 kgm3, 2% more than water. Calculate the new velocity of the water under these new conditions. 5. Inertia is an important factor in understanding the interior characteristics of an object. Explain how the mass factors in the moment of inertia and density relate to Newton's 1 law and how they explain the behavior of objects when a force is applied to them. v (m/s) Speed 1.00 0.500 0.00 5.00 t(s) Figure 1: Velocity vs. time plot of a 100.0 kg object. 0.00 10.0 15.0
