An iron robot falls from rest at a great height. neglecting air resistance, what is its speed after it has fallen for 3.5 seconds? 13.3 m/s 9.8 m/s 34.3 m/s 9.8 m/s2

In an uniformly accelerated motion, the velocity of the object follows the law:

where  is the initial velocity, a the acceleration and t the time.

In our problem, the robot starts from rest, so the initial speed is zero: . The robot is in free fall, so the acceleraion is the gravitational acceleration . therefore, after a time , the velocity is 

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
