An Olympic diver is on a diving platform 4.5 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction. You will be asked to find the diver's speed just before she enters the water.  What are the givens in the y-direction?    v0y = 1.3 m/s; ay = -9.8 m/s2; Δy = 4.5 m    v0y = 0 m/s; ay = -9.8 m/s2; Δy = 4.5 m    v0y = 1.3 m/s; ay = 0 m/s2; Δy = -4.5 m   v0y = 0 m/s; ay = -9.8 m/s2; Δy = -4.5 m

v0y = 1.3 m/s; ay = -9.8 m/s2; Δy = 4.5 m
  
v0y = 0 m/s; ay = -9.8 m/s2; Δy = 4.5 m
  
v0y = 1.3 m/s; ay = 0 m/s2; Δy = -4.5 m
 
v0y = 0 m/s; ay = -9.8 m/s2; Δy = -4.5 m
