WebMiranda, a satellite of Uranus, is shown in Figure P13.5a. It can be modeled as a sphere of radius 242 km and mass 6.68 1019 kg. (a) Find the free-fall acceleration on its surface. (b) A cliff on Miranda is 5.00 km high. It appears on the limb at the 11 oclock position in Figure P13.5a and is magnified in Figure P13.5b. WebAug 29, 2006 · At 6 seconds, (free-fall value of t=4)/4. v = -19.6 m/s ... "The acceleration of the stone (due to gravity) is constant. Therefore, the slope of the velocity vs. time graph is constant." ... "The velocity of the stone becomes negative after it reach its highest point." I'm not even sure I was even finding the velocity before, or just ...

WebA ball is shot vertically upward from the surface of another planet. A plot of y versus t for the ball is shown in Fig, where y is the height of the ball above its starting point and t = 0 at the instant the ball is shot. The figure’s vertical scaling is set by y s = 3 0. 0 m. What are the magnitudes of the free-fall acceleration on the planet? i hear bells in my ears
