Q1. A pebble is dropped down a well and hits the water 1.19 s later. Using the equations for motion with constant acceleration, determine the distance from the edge of the well to water's surface.

Q2. A hotel elevator ascends 140 {rm m} with a maximum speed of 4.59 {rm m/s}. Its acceleration and deceleration both have the magnitude of 1.93 {rm m/s^2}. How long does it take to make complete trip from bottom to top?
