Rhoda tiller looks up to see a flowerpot fall off a ledge 9.2 m above her head. how long does she have to react and move before being hit on the head?

The flowerpot is in free fall, so it moves by uniformly accelerated motion with acceleration equal to . Its initial speed is zero, so we can write the law of motion for the pot as

where S(t) is the distance covered by the pot after a time t.
We want to find the time t at which the pot reaches ground, so the time t after which the pot has covered 9.2 m, therefore we should require S(t)=9.2 m and find t:

4. 50x10= 500m/s 5. 52m/s
