The acceleration of gravity is found by dropping a ball from various heights. The data for the experiment is as follows: Distance, d (meters): 15.43 17.37 19.62 21.68 Time, t (seconds): 1.804 1.915 2.043 2.149 a.) Copy these data and add a third row which contains the calculated accelerations due to gravity as given by g = 2d/t^2. b.) By finding the mean and standard deviation, show that the answer is inconsistent with the accepted value of g = 9.80...
In general relativity, gravity changes time. Gravity potential o =-GM/R. Time change r= At/t= AQ / c2. If uncorrected, it would cause errors in GPS Global Positioning System. The GPS satellites orbit average 20,200 km above Earth surface, and gravity at the satellites are a little different from Earth surface. Find the: a) time error r ? e-10 due to gravity. b) distance error (km) in one day. (signal travels at light speed)
28. In a simple pendulum experiment for determination of acceleration due to gravity (g), time taken for 20 oscillations is measured by using a watch of 1 second least count. The mean value of time taken comes out to be 30 s. The length of pendulum is measured by using a meter scale of least count 1 mm and the value obtained is 55.0 cm. The percentage error in the determination of g is close to (a) 0.7% (b) 6.8%...

The acceleration due to gravity g near the surface of the Earth can be measured by projecting an object vertically upward and measuring the time that it takes to pass two given points in both directions. See the diagram below. Notice that the horizontal axis is time not position the path of the object is purely along a straight, vertical line. Show that if the time the body takes to pass a horizontal...
a baseball is hit when it is 3ft above the ground It leaves the
bat with initial speed of 155 ft/sec
A baseball is hit when it is 3 ft above the ground. It leaves the bat with initial speed of 155 ft/sec, making an angle of 16 questions with the horizontal. Assume there is linear drag with a drag coefficient k0.31. The acceleration due to gravity is g-32 ft/sec Answer the following ( sin a)1-k-) equations for linear drag,...
