🤓 Based on our data, we think this question is relevant for Professor Di Credico's class at NEU.

Solution: A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 1.90 s. You may ignore air resistance, so the brick is in free fall.(a) How tall, in meters, is the building?(b) What is the magnitude of the brick’s velocity just before it reaches the ground? 

Problem

A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 1.90 s. You may ignore air resistance, so the brick is in free fall.
(a) How tall, in meters, is the building?
(b) What is the magnitude of the brick’s velocity just before it reaches the ground?
