An object travels in a vertical circle of 1.50 m radius. When the object is traveling downward and is 31.5° from its lowest point, its total acceleration is  a = (18.5î + 16.2ĵ) m/s2.  At this instant, determine the following. (Take the angle 31.5° clockwise from the axis of the circle that intersects the center and the lowest

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.33 m above the floor. The ball hits the floor 0.365 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     40.0 m/s^2     20.0 m/s^2     10.0 m/s^2     15.0 m/s^2

An object travels in a vertical circle of 1.43 m radius. When the object is traveling downward and is 28.0° from its lowest point, its total acceleration is a = (18.51 + 16.2ĵ) m/s². At this instant, determine the following. (Take the angle 28.0° clockwise from the axis of the circle that intersects the center and the lowest point.

You are exploring a planet and drop a small rock from the edge of a cliff. In coordinates where the +y direction is downward and neglecting air resistance, the vertical displacement of an object released from rest is given by y − y0 = 1/2gplanett2, where gplanet is the acceleration due to gravity on the planet. You measure t in seconds for several values of y − y0 in meters and plot your data with t2 on the vertical axis and y − y0 on the horizontal axis. Your data is fit closely by a straight line that has slope 0.300 s2/m. Based on your data, what is the value of gplanet?
