Problem 46PE

A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.00 m/ s, and her takeoff point is 1.80 m above the pool. (a) How long are her feet in the air? (b) What is her highest point above the board? (c) What is her velocity when her feet hit the water?

Step-by-Step Solution:

Step-by-step solution 46PE Step 1 of 5 The time can be calculated from the equation of the motion, Here, s is the displacement, u is the initia l velocity, t is the time interval and a is the acceleration of the body. Step 2 of 5 (a) The above equation is the quadratic equation in time t that can be solved as, Substitute for , 1.80 m fo r s and for a. Take negative sign in above formula for positive value of time. Step 3 of 5 Hence, the time while her feet were in the air is .
