Concept explainers
Referring to Example 4-11 Suppose the ball is dropped at the horizontal distance of 5.50 m, but from a new height of 5.00 m. The dolphin jumps with the same speed of 12.0 m/s. (a) What launch angle must the dolphin have if it is to catch the ball? (b) At what height does the dolphin catch the ball in this case? (c) What is the minimum initial speed the dolphin must have to catch the ball before it hits the water?

- 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_forwardA projectile launcher is clamped to a bench with the muzzle 0.85 m from the floor. It launches a small ball at an angle of 35° with a velocity of 15.5 m/s. The ball travels freely until it eventually hits the floor, assuming no air resistance or draughts calculate the following: a) The time it takes to reach its maximum height. b) The maximum height of the ball above the floor. c) The total time the ball spent in the air d) The total distance travelled horizontally by the ball from the end of the muzzle to its first impact with the floor.arrow_forwardThe maximum horizontal distance a boy can throw a ball is 50 m. Assume he can throw with the same initial speed at all angles. How high does he throw the ball when he throws it straight upward?arrow_forward
- a locusts jumps at an angle 55 above horizontal and lands 0.80m where it jumped.calculate the (a) maximum height of the locusts during its jump.ignore air resistance (b) time of flight of the locus (c) if it jumps with the same initial speed at an angle of 45,would the maximum height be larger or smaller? explain your answer qualitatively.arrow_forwardYou are at the edge of the cliff at a height of 50 m. calculate how long it would take for a stone to hit the ground in each of the three cases. you just drop the stone from rest, you throw the stone with a speed of 18.5 m/s in a horizontal direction, you throw the stone with the same initial speed, but an angle of 30° above the horizontal. Also calculate how far from the foot of the cliff the stone lands in each case described above ( i.e. the horizontal range in each case.)arrow_forwardConsider a ball tossed over a fence. Construct a problem in which you calculate the ball's needed initial velocity to just clear the fence. Among the things to determine are; the height of the fence, the distance to the fence from the point of release of the ball, and the height at which the ball is released. You should also consider whether it is possible to choose the initial speed for the ball and just calculate the angle at which it is thrown. Also examine the possibility of multiple solutions given the distances and heights you have chosen.arrow_forward
- A man stands on the roof of a 15.0 m tall building and throws a rock with a speed of 30.0 m/s at an angle of 35° above the horizontal. Ignore air resistance. Calculate (a) the maximum height above the roof that the rock reaches. (b) the speed of the rock just before it strikes the ground; and (c) the horizontal range from the base of the building to the point where the rock strikes the ground.arrow_forwardA large cannon is fired from ground level over level ground at an angle of 300 above the horizontal. The muzzle speed is 980 m/s. Neglecting air resistance, answer the following questions: a) what is the maximum height that the projectile will reach? b) how long till the projectile will hit the ground? c) the projectile will travel what horizontal distance before striking the ground?arrow_forwardA baseball is thrown with an initial speed of 37.5 m/s at a 42.0° angle in the absence of air resistance. a) What is the maximum height reached by the baseball? b) What is the magnitude and direction of the baseball's velocity at t = 2.50 s? c) What is the ball's height when it has traveled a horizontal distance of 55.0 m?arrow_forward
- A golfer is attempting to reach the elevated green by hitting his ball under a low-hanging branch in one tree A, but over the top of a second tree B. If the launch speed of the golf ball is vo = 115 mi/hr, what launch angle 0 will put the first impact point of the ball closest to the pin? How far from the pin (distance d) is this impact point?

The ball lands 100m down range from the base of the building. What was the initial speed of the ball? Neglect air resistance and use g = 9.8m / s * 2arrow_forwardIn a carnival booth, you win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.1 m from this point. If you toss the coin with a velocity of 6.4 m/s at an angle of 60° above the horizontal, the coin lands in the dish. You can ignore air resistance,a) What is the height of the shelf above the point where the quarter leaves your hand? b) What is the vertical component of the velocity of the quarter just before it lands in the dish?arrow_forward
