(II) (a) A long jumper leaves the ground at 45° above the horizontal and lands 8.0 m away. What is her “takeoff” speed v0? (b) Now she is out on a hike and comes to the left bank of a river. There is no bridge and the right bank is 10.0 m away horizontally and 2.5 m, vertically below. If she long jumps from the edge of the left bank at 45° with the speed calculated in (a), how long, or short, of the opposite bank will she land (Fig. 3–43)?

- Not 48 60 In Fig. 4-41, a ball is thrown up onto a roof, landing 4.00 s later at height h 20.0 m above the release level. The ball's path just before landing is angled at e3 60.0° with the roof. (a) Find the horizontal distance d it travels. (See the hint to Problem 39.) What are the (b) magnitude and (c) an- gle (relative to the horizontal) of the ball's initial velocity? 0000 వెరం్ 2 ర 500 0000 9992000-8009 Flg. 4-41 Problem 48.arrow_forward(i) In 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 (Fig. E3.19). If you toss the coin with a velocity of 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 and What is the vertical component of the velocity of the quarter just before it lands in the dish.arrow_forward(i) As a projectile thrown at an upward angle moves in its parabolic path (as shown), at what point along its path are the velocity and acceleration vectors for the projectile perpendicular to each other? (a) nowhere (b) the highest point (c) the launch point (ii) From the same choices, at what point are the velocity and acceleration vectors for the projectile parallel to each other?arrow_forward
- e45 In Fig. 4-40, a ball is launched with a velocity of magnitude 10.0 m/s, at an angle of 50.0° to the horizontal. The launch point is at the base of a ramp of horizon- tal length d = 6.00 m and height d, = 3.60 m. A plateau is located at the top of the ramp. (a) Does the ball land on the ramp or the plateau? When it lands, what are the (b) mag- nitude and (c) angle of its dis- placement from the launch point? Vo A d2 Ball di Figure 4-40 Problem 45.arrow_forward(8) Please don't write on a paper. I can't understand handwritten. A toy giraffe was thrown horizontally from the edge of the table at a velocity of 7.5 m/s. If the table is 1.25 m high, what is the toy's velocity just before it hits the ground?arrow_forwardBased on a grade 11 physics student, answer the following question: A poké-ball rolls off Ash’s table with a velocity of 1.93 m/s [horizontally]. The tabletop is 76.5 cm above the floor. If air resistance is negligible, determine how long the poké-ball is airborne the horizontal range (distance) the velocity at impactarrow_forward
- 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?arrow_forwardImagine that you hit a ball at ground level and send it toward the wall with a speed at 18 m/s at an angle of 32° above the horizontal. (a) How long does it take for the ball to reach the wall if it is 3.8 m away. (b) How high is the ball when it hits the wall?arrow_forwardCan you help me with this question? A motocyclist drives his bike off of a 12 m high horizontal ledge. If he is driving at a speed of 22 m/s horizontally, how far from the base of the ledge does he land?arrow_forward

Neglecting air resistance and thecurvature of the earth, calculate:a) the distance from the cannon where the ball strikes the groundb) the maximum height to which the cannonball risesarrow_forwardIn 1939 or 1940, Emanuel Zacchini took his human-cannonball act to an extreme: After being shot from a cannon, he soared over three Ferris wheels and into a net (see the figure). Assume that he is launched with a speed of 26 m/s and at an angle of 50°. (a) Treating him as a particle, calculate his clearance over the first wheel.
