*73. mmh A golfer, standing on a fairway, hits a shot to a green that is elevated 5.50 m above the point where she is standing. If the ball leaves her club with a velocity of 46.0 m/s at an angle of 35.0° above the ground, find the time that the ball is in the air before it hits the green.

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.8m/s at an angle of 23 degrees SE from the window (downwards, not upwards). It hits the ground 5s later. a. How far horizontally from the building does the ball land on the ground? b. Find the height that the ball was thrown from

A rescue plane flies at 198km/hr and at a constant elevation of 500m toward a point directly over an accident victim struggling in the sea. The pilot must release a rescue capsule so that it hits the water very close to the victim.a). what should be the angle of the pilot’s line of sight when the capsule is released? EVb) what is the velocity of the rescue in the vertical plane when the capsule is released? APc). as the capsule reaches the water, what is its velocity ?̅in i. the unit vector notation? ANii. magnitude- angle notation

An object undergoing projectile motion travels 2.50 x 10² m in the horizontal direction before returning to its initial height. Neglect any effects due to air resistance. If the object is thrown initially at a 30.0° angle from the horizontal, determine the x-component vix of the initial velocity. Ui.x = m/s determine the y-component v₁y of the initial velocity. Ui.y = DIL DD m/s Question Source: Freedman College Physics 3e | Publisher: Macmillan

A projectile is launched at an angle of 30°to the horizontal from 6.5 ft above the ground at an initial speed of 100​ft/sec. Assume the​ x-axis is​ horizontal, the positive​ y-axis is vertical​ (opposite g), the ground is​ horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors for t≥0. b. Determine the time of flight and range of the object. c. Determine the maximum height of the object.

A football player kicks the ball at a 45.0 degrees angle. Without an effect from the wind the ball would travel 50.0 meters horizontally. Hint a. What is the initial speed of the ball in meters per second. m/s b. When the ball is near its maximum height it experiences a brief gust of wind that reduces its horizontal velocity by 2.50 m/s. What distance in meters does the ball travel horizontally? m

1. Vo = 20.0 m/s S0.0° (0,0) 45.0 m (x, – 45.0 m) A ball is thrown upward from the top of a building at an angle of 30.0° to the horizontal and with an initial speed of 20.0 m/s, as in the figure. The point of release is 45.0 m above the ground. (a) How long does it take for the ball to hit the ground? (b) Find the ball's speed at impact. (c) Find the horizontal range of the ball. Neglect air resistance.
