1. The problem statement, all variables and given/known data While riding on an elevator descending with a constant speed of 3.3 m/s, you accidentally drop a book from under your arm. (a) How long does it take for the book to reach the elevator floor, 1.0 m below your arm? (b) What is the book's speed relative to you when it hits the elevator floor? 2. Relevant equations v = v0 + a*t x = x0 + v0 *t + 1/2*a*t^2 x= x0 + v*t-1/2*a*t^2 V^2 = v0^2 +2*a*(x-x0) 3. The attempt at a solution I tried to solve for time by first solving for final velocity using V^2 = v0^2+2*a*(x-x0) = V^2 = (3.3m/s)^2 +2(-9.80m/s^2)(0-1m) V^2 = 30.49 m^2/S^2 square root of 30.49 = 5.522 m/s v = v0 +a*t 5.522 = 3.3 + (9.80)*t t = 0.2267 part b) substract the book's velocity 5.522 - my velocity 3.3 = 2.222 I got both answers wrong. I was wondering if someone could help me explain what i did wrong? thank you so much!
