progamerz Posted October 14, 2016 Posted October 14, 2016 The question is: A ball takes 5s to hit the ground, when dropped from the top of the building. What is the height of the building? And the answer is: My question is how we got g and is gravitation force denoted as g or what is g? I have exam on this sunday Thanks. 1
Decode Posted October 14, 2016 Posted October 14, 2016 g is the gravitational force. Since it was 'dropped' from a building the acceleration of the ball is gravity.

This is first year for me in physics, So i am completely new but i mean how they got g = 9.8m/s2? Thank you for trying to help.

Arjen Posted October 14, 2016 Posted October 14, 2016 This is first year for me in physics, So i am completely new but i mean how they got g = 9.8m/s2? Thank you for trying to help. because the gravity on earth pulls with 9.8m per second.. on the moon its 1.6m per second.. on earth its always 9.8 1
