MY NOTES ASK YOUR TEACHER An arrow is fired with initial velocity vo at an angle 0 from the top of battlements, a height h above the ground. (Assume # is measured above the horizontal.) (a) In terms of h, Vo, 0, and g, what is the time at which the arrow reaches its maximum height? V sin 0 t = g X (b) In terms of h, Vo, 0, and g, what is the maximum height above the ground reached by the arrow? sin e hmax = h+ 2g X Need Help? Read It Submit Answer 4. [3.32/5 Points] DETAILS PREVIOUS ANSWERS KATZPSEF1 4.P.033. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Dock diving is a great form of athletic competition for dogs of all shapes and sizes. Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.32 m/s at an angle of 230 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 0.90 m above the surface of the water, through what horizontal distance does she travel before hitting the surface of the water? 8.053 vm (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.) V = 8.579i - 5.551j m/s (c) Determine the peak height above the water reached by Sheba during her jump. 2.675 X Your response differs from the correct answer by more than 10%.
