PHYSICS 1403 Lab Homework-Calculating Gravitational Acceleration This homework will be due when you come to lab the week of October 23. is stranded on a distant planet. He needs to send a message rocket home so he can be In order to launch the rocket successfully, the astronaut must know the acceleration of gravity ethi punt He takes the following data by dropping a rock from the top of a tree: Position Trial 1 (m) Position Trial I (m) Position Trial 1 (m) Average Position (m) Time 4.135 4.162 16.94 37.20 4.21 16.05 38.02 65.9866.24 3.0 37.505 Calculate the average position of the rock. Assume the initial velocity of the rock is zero. On a separate sheet of graph paper, plot the average position versus the square of the time to find the acceleration due to gravity. Write the value below:

Explanation / Answer

we will use the concept that dimension of acceleration = [m/ sec2];

Given in 4 sec = 66.8 m

=> a= 66.8/42=4.175 m / s2
