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 0 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 (b) In terms of h, Vor 0, and g, what is the maximum height above the ground reached by the arrow? 21 sin (20) hmax = g Need Help?

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? (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. m Need Help? Read It Submit Answer5.

The canoe moves downstream with constant speed 5 m/s relative to the water. The river has a steady current of 1 m/s relative to the bank. The man's hat falls into the river. Nine minutes later, he notices that his hat is missing and immediately turns the canoe around, paddling upriver with the same constant speed of 5 m/s relative to the water. How long does it take the man to row back upriver to reclaim his hat? 14 X Your response differs from the correct answer by more than 10%. Double check your calculations. min Need Help?

Kit the cat is going to jump through a hoop. He begins on a wicker cabinet at a height of 1.755 m above the floor and jumps through the center of a vertical hoop, reaching a peak height 3.105 m above the floor. (Assume the center of the hoop is at the peak height of the jump. Assume that +x axis is in the direction of the hoop from the cabinet and +y axis is up. Assume g = 9.81 m/s2.) (a) With what initial velocity did Kit leave the cabinet if the hoop is at a horizontal distance of 1.530 m from the cabinet? (Express your answer in vector form. Give your answer to at least two decimal places for each vector component.) Vo : m/s (b) If Kit lands on a bed at a horizontal distance of 3.593 m from the cabinet, how high above the ground is the bed? m Need Help?
