A golfer hits a shot to a green that is elevated 3.30 m above the point where the ball is struck. The ball leaves the club at a speed of 17.0 m/s at an angle of 46.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.

Problem 10: While watching the clouds pass by, you notice a European swallow flying horizontally at a height of h = 21.95 m. When the swallow is directly overhead, it drops an m = 10.5 kg coconut. Refer to the diagram. From your ornithological studies, you know that the air-speed of this particular species of swallow, while carrying such a load, is vo = 6.93 m/s. Neglect air resistance. Assume that your head is at the origin of the coordinate system. Part (a) Calculate the magnitude, in kilogram squared meters per second, of the angular momentum of the coconut, as observed by you, at the moment it is released directly overhead. L = 1597.19 L= 1597 V Correct! Part (b) Let 7 be the time-dependent position vector of the coconut with time measured from the instant it was released by the swallow. Enter an expression for its horizontal component as a function of time. r(1) = vot v Correct! Part (c) Enter an expression, in unit vector notation, for the time-dependent velocity vector, v(1), of…

A student fires a cannonball diagonally upwards with an initial speed v at an angle 0 as shown. Determine all unknowns and answer the following questions. Neglect drag and the initial height of the cannonball. Calculate the total flight time (t) and range (r) in each of the following cases. v [m/s] e [º] t [s] r [m] 30.0 40.0 50.0 60.0 60.0 55.0 55.0 55.0 55.0 75.0 00000 0

While at bat, your baseball teams star hitter strikes a 145-gram ball with an initial velocity of 34.7 m/s at 40.1 degrees above the horizontal. Ignoring air resistance, find the maxium height reached by the ball above its starting location in meters.
