1. The problem statement, all variables and given/known data

An elevator ascends with an upward acceleration of 1.2m/s^2. At the instant its upward speed is 2.4 m/s, a loose bolt drops from the ceiling of the elevator 2.7m from the floor. Calculate the time of flight of the bolt from ceiling to floor and the distance its has fallen relative to the elevator shaft.

3. The attempt at a solution

s1 = 2.4t - (1/2)gt^2

s2 = 2.4t + (1/2)(1.2)t^2

2.7= -2.4t + (1/2)gt^2 + 2.4t + (1/2)(1.2)t^2

2.7 = (1/2)[9.8 + 1.2]t^2

2.7 = 5.5t^2

t = √(2.7/5.5) = 0.7 seconds

s1 = 2.4(0.7) - (1/2)(9.8)(0.7)^2

s1 = -0.724 meters

Just wondering is the answer right or not.
