A ball is thrown downward from the top of a 15m-building at an angle of 30° with the horizontal.
a) If the ball is thrown with a speed of 6.0 m/s how far from the edge of the building does the ball strikes the ground?
b) If there is a 1.7 m tall man standing 5.0 m from the edge of the building at a bus stop will the ball hit him?
When a field goal kicker kicks a football as hard as he can at 45° to the horizontal, the ball just clears the 3-m high crossbar of the goalposts 45.7 m away. (a) What is the maximum speed the kicker can impart to the football? (b) In addition to clearing the crossbar, the football must be high enough in the air early during its flight to clear the reach of the onrushing defensive lineman. If the lineman is 4.6 m away and has a vertical reach of 2.5 m, can he block the 45.7-m field goal attempt? (c) What if the lineman is 1.0 m away?
A basketball player is shooting some hoops, on one particular shot the ball leaves her hands 11.7m horizonally away from the hoop, and 2.1m vertically off the ground. Let's say she shoots a particular shot with a velocity of 15m/s at an angle of 63.4° with respect to the vertical (Assume no air resistance)
Part A) Find the horizontal and vertical components of the angled velocity vector.
Part B) Find the time it takes the ball to reach the hoop.
Part C) Assuming she makes her basket find the height of the hoop

Between what two angles, 8₁ and ₂, will the ball clear the 2.57-m-high crossbar? Give your answers as (a) the smaller angle and (b) the larger angle. (Hint: The following trigonometric identities may be useful: sec 0-1/(cos) and sec²0-1+tan²8.) (a) Number i (b) Number i Units Unitsarrow_forwardIn 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38° will give a longer range than 45° in the shot put.)arrow_forwardTwo golf balls are hit from the same point on a flat field. Both are hit at an angle of 45° above the horizontal. Ball 2 has three times the initial speed of ball 1. If ball 1 lands a distance ?1 from the initial point, at what distance ?2 does ball 2 land from the initial point? Neglect any effects due to air resistance.arrow_forward
