**A 5m tall elevator travels uniformly up an elevator shaft at 8m/s. At some point in time, a bolt falls from the top of the elevator and falls freely down the shaft. You can ignore the effect of air resistance.**

How many seconds after the fall will the bolt pass the bottom of the elevator?

How many seconds after the fall will the bolt pass the bottom of the elevator?

**y=yi + vit + (1/2)at^2**

**I tried to use the above equation for both the elevator and the bolt separately. The bolt takes 1.01 seconds to fall 5m and the elevator moves up 5m in 0.625 seconds.**
