|| The longest home run. According to the Guinness Book of World Records, the longest home run ever measured was hit by Roy “Dizzy” Carlyle in a minor-league game. The ball traveled 188 m (618 ft) before landing on the ground outside the ballpark. (a) Assuming that the ball’s initial velocity was 45° above the horizontal, and ignoring air resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9 m (3.0 ft) above ground level? Assume that the ground was perfectly flat. (b) How far would the ball be above a fence 3.0 m (10 ft) in height if the fence were 116 m (380 ft) from home plate?

- In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.arrow_forward7. A ball is kicked at 10.4 m/s at an angle of 32° to the horizontal. a) How long (time) is the ball in the air?

Which one of the following statements is true? O The acceleration of the ball decreases as the ball moves upward. O The velocity of the ball is O when the ball is at the highest point in the arc. O The acceleration of the ball is 0 when the ball is at the highest point in the arc. O The velocity of the ball is a maximum when the ball is at the highest point in the arc. O None of the above.arrow_forward

The ball travelled 188m before landing on the ground outside the ballpark. Assuming the ball's initial velocity was in direction 45° above the horizontal, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9m above ground level?

(Select all that apply.) O It has zero acceleration. It has an acceleration directed away from the center of its path. It has an acceleration component in the direction of its velocity. It has an acceleration with a direction that cannot be determined from the information given. O It has an acceleration directed toward the center of its path.arrow_forwardTwo youngsters dive off an overhang intoa lake. Diver 1 drops straight down, and diver 2 runs off the cliffwith an initial horizontal speed v0. (a) Is the splashdown speed ofdiver 2 greater than, less than, or equal to the splashdown speed ofdiver 1? (b) Choose the best explanation from among the following:I. Both divers are in free fall, and hence they will have the samesplashdown speed.II. The divers have the same vertical speed at splashdown, butdiver 2 has the greater horizontal speed.III. The diver who drops straight down gains more speed than theone who moves horizontally.arrow_forward

The cannon releases him at the same height as the net. His initial velocity is 18.3 m/s in a direction 40.0° above the horizontal. a) For how much time will he be in the air? b) How far does he travel horizontally? c) What is the velocity upon impact? The circus manager from the previous question wants to make the stunt more dramatic by firing the stuntman through a hoop 9.0 m high then land in a safety net at the same height as the cannon. The cannon’s angle is changed to 45.0° and the velocity is increased to 21.0 m/s. The manager needs to know where to place the hoop and safety net. a) How far from the cannon should the safety net be placed? b) What is the time required to reach the height of the hoop? c) How far from the cannon should the hoop be placed?arrow_forward
