Question

A body is dropped from the top of the tower 200ft high has an initial velocity of 25ft/sec.What will velocity of the body after 1 sec of life? ​​

Answer 1

Answer:

Explanation:For the velocity in the vertical (y) direction, the speed as a function of time v(t) is just

v(t)=v(0)-gt

We know v(0)=-25 fps,

v(t)=-25–32.2t

Therefore,

v(1)=-25–32.2(1)=-25–32.2=-57.2 fps

Solution: v(1)=-57.2 fps
