Question

3 formula 1 point a worker drops their hard hat while they are up on scaffolding. the hat started at a height of 10.3 meters. assuming that ground level is at a height of 0 meters, what must be the displacement of the hat when it strikes the ground? answer

Explanation:

Step1: Define displacement

Displacement is the change in position.

Step2: Calculate displacement

Initial height $h_i = 10.3$ m, final height $h_f=0$ m. Displacement $\Delta h=h_f - h_i=0 - 10.3=- 10.3$ m. The negative sign indicates the direction is down - ward. The magnitude of displacement is 10.3 m.

Answer:

10.3 m
