Question

What equation would I use to solve this?:
How long would it take a bolt dropped from a 1.3m ladder to reach the ground?

Answer 1

@electrokid

Answer 2

this is a vertical translational kinematics problem.
we have:
displacement = -1.3m
acceleration = -9.81 m/s^2
initial velocity = 0m/s (since it is just dropped!)

to find = time = t

which of the three kinematic equations connects all the "4" quantities?

Answer 3

I used d = vi*t + .5at^2 and got .515s Is that correct?

Answer 4

yes.
good job

Answer 5

Thanks!
