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 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.
