Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.12 m/s at an angle of 22° with respect to the surface of the water. (Assume that the +x axis is in the direction of the run and the +y axis is up.) (a) If Sheba begins at a height of 0.71 m above the surface of the water, through what horizontal distance does she travel before hitting the surface of the water? 7.312 m (b) Write an expression for the velocity of Sheba, in component form, the instant before she hits the water. (Express your answer in vector form.) m/s (c) Determine the peak height above the water reached by Sheba during her jump. Your response differs from the correct answer by more than 10%.
