Unformatted text preview: 2 1 2 y sin y = and finally ( 29 1 2 2 2 o y 5.5m y 7.3m sin sin60 = = = 2) A diver runs horizontally with a speed of 1.20 m/s off a platform that is 10.0 m above the water. What is his speed just before striking the water? The x component of velocity is v x = 1.2 m/s and is constant The y component of velocity satisfies the following: ( 29 ( 29 2 2 2 2 2 y 0 y y m m v v 2a y 2 9.8 10m 196 s s = + = + = The final speed is: 2 2 x y v v v 1.44 196 14.05m / s = + = + =...
