Concept explainers
Tarzan and Jane. Tarzan, in one tree, sights Jane in another tree. He grabs the end of a vine with length 20 in that makes an angle of 45° with the vertical, steps off his tree limb, and swings down and then up to Jane’s open arms. When he arrives, his vine makes an angle of 30° with the vertical. Determine whether he gives her a tender embrace or knocks her off her limb by calculating Tarzan’s speed just before he reaches Jane. Ignore air resistance and the mass of the vine.

- If the car's speed were not reduced by any structural effects or by friction, how long would it take to complete the race? What is the speed of the car at the end of the race?arrow_forwardHello, there are several variables I have had to find for this problem but I am stuck on figuring out the last two. Please help! Thank you. A rock is thrown off a cliff at an angle of 60∘ with respect to the horizontal. The cliff is 128 m high. The initial speed of the rock is 32 m/s. Known:v0= 32 m/s v0x= 16 m/s v0y= 27.6 m/s Δy= 39.12 m t(ground)= 8.76 s Δx(total)= 138.72 m Unknown: How far has it moved horizontally when it is at maximum altitude? Δx= ? What are the horizontal and vertical positions of the rock relative to the edge of the cliff at t = 4.4 s. Assume that the origin (0,0) for this part is loacted at the edge of the cliff. Enter the positions with their correct signs. Position: (x= ? , y= ?)marrow_forwardIt's been a great day of new, frictionless snow. Julie starts at the top of the 60° slope with a push-off velocity of 1.7 m/s as shown in the diagram. At the bottom a circular arc carries her through a 90° turn, and then she launches off a 3.0-m-high ramp. How far horizontally is her touchdown point (in m) from the end of the ramp assuming that air resistance is negligible and that the local acceleration due to gravity is 9.80 m/s2?arrow_forward
- A skier with a mass of 63.0 kg starts from rest and skis down an icy slope that has a length of 53.0 m at an angle of 32 degrees with respect to the horizontal. At the bottom of the slope, the path levels out and becomes horizontal, the snow becomes less icy, and the skier begins to slow down, coming to rest in a distance of 122m along the horizontal path. What is the speed of the skier at the bottom of the slope? What is the coefficient of kinetic friction between the skier and the horizontal surface?arrow_forwardOn the Martian moon of Phobos, the escape speed is only 11.3 m/s . While standing on Phobos, suppose a person throws a baseball at a speed equal to the escape speed. The figure shows four possible directions in which the person could throw the ball at that speed.In which of these directions will the ball escape from Phobos? Could I please have some direction on how I may approach this? direction A only direction A or B direction A, B, or C direction A, B, C, or D none of thesearrow_forwardTwo frogs of equal masses jump into the air with the same initial speed. Frog #1 goes straight up, while frog #2 goes up at a 73° angle above the horizontal. Assuming negligible air resistance, which of the following statements about the two frogs are correct?(There could be more than one correct choice.) A) At their highest point, frog #2 is moving faster than frog #1.B) At their highest point, both of them have the same amount of gravitational potential energy. C) At their highest point, both of them have the same amount of kinetic energy.D) At their highest point, both of them have the same amount of mechanical energy.E) At their highest point, frog #1 has more gravitational potential energy than frog #2arrow_forward
- A golfer hits a shot to a green that is elevated 2.50 m above the point where the ball is struck. The ball leaves the club at a speed of 19.5 m/s at an angle of 40.0° above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands. V = iarrow_forwardConsider the vectors A = 2.0i - 4.0j + k, B = 3.0i + 4.0j + 10.0k, C = -3.0i - 4.0j, D = -3.0i + 4.0j, E = -2.0i + 3.0j + 2.0k, F = -9.0j. a)What is A × B? Give your answer in the form of "ai + bj + ck". b)What is B × A? Give your answer in the form of "ai + bj + ck". c)What is C × D? Give your answer in the form of "ai + bj + ck". d)What is F × E? Give your answer in the form of "ai + bj + ck".arrow_forwardAlice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below (select all answers that are true) Group of answer choices: None of the above choices are correct. they will both have the same speed. the speed of Alice is larger than that of Tom. Alice reaches the surface of the lake first. They reach the surface of the lake at the same time. Tom reaches the surface of the lake first. the speed of Tom is larger than that of Alice.arrow_forward
- g12 physicsarrow_forwardAn adventurous archeologist (m = 85.5 kg) tries to cross a river by swinging from a vine. The vine is 11.0 m long, and his speed at the bottom of the swing is 7.50 m/s. The archeologist doesn't know that the vine has a breaking strength of 1,000 N. Does he make it safely across the river without falling in? Yes Noarrow_forwardIn the figure, a stone is projected at a cliff of height h with an initial speed of 45.0 m/s directed at an angle 80 = 64.0° above the horizontal. The stone strikes at A, 5.26 s after launching. Find (a) the heighth of the cliff, (b) the speed of the stone just before impact at A, and (c) the maximum height H reached above the ground.
