- Figure 1.18 (Chapter 1) shows the Hoover Dam Bridge over the Colorado River at a height of 271 m. If a heavy object is dropped from the bridge, how much time passes before the object makes a splash?A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.Elisha Graves Otis invented the elevator brake in the mid-1800s, making it possible to build tall skyscrapers with fast elevators. Todays skyscrapers are a large fraction of a mile tall; for example. Taipei 101 in Taiwan has 101 stories and is 515 m (0.32 miles) tall. The top speed of the elevator in the Taipei 101 tower is roughly three times greater than the ascent rate of a commercial jet airplane. The position and time data in the table are based on such an elevator. a. Working in SI units, make a position-versus-time graph for the elevator. (You may wish to use a spreadsheet program.) b. Describe the motion of the elevator in words. c. Find the highest speed of the elevator. When is the elevator going at this speed? d. What sort of considerations would the engineers need to make to ensure the comfort of the passengers?
- 4. You drop a ball from a height of 100 metres. Each time it bounces 70% of the previous height. a. Write a rule for the height of the ball after the ??th bounce.b. Find the total vertical distance of the ball has travelled when it hits the ground for the7th time? (Answer in 2 decimal places if applicable)Pp#2: Hello, this is my second attempt sending this practice problem. I was told it was incomplete. What do you mean by that?

Thank you.A soft tennis ball is dropped onto a hard floor from a height of 1.85 m and rebounds to a height of 1.41 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. 3.5 m/s - WRONG (b) Calculate its velocity just after it leaves the floor on its way back up. 6.02 m/s - WRONG (c) Calculate its acceleration during contact with the floor if that contact lasts. 3222.76 - RIGHT (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid????
- A ball is thrown straight up with enough speed so that it is in the air for several seconds. Assume the positive direction is upwards. Part A - What is the velocity of the ball when it reaches its highest point Part B - What is its velocity 0.70s before it reaches its highest point? Part C - What is the change in its velocity, v, during this 0.70s interval? Part D - What is its velocity 0.70s after it reaches its highest point? Part E - What is the change in velocity, v, during this 0.70s interval? Part F - What is the change in velocity, v, during the 1.4s interval from 0.70s before the highest point is 0.70s after the highest point? (Caution: we are talking about velocity not speed) Part G - What is the acceleration of the ball during any of these time interavals and at the moment the ball has zero velocity?When salmon head upstream to spawn, they may encounter a waterfall. If the water is not moving too fast, the salmon can swim right up through the falling water. Otherwise, the salmon jump out of the water to get to a place in the waterfall where the water is not falling so fast. When humans build dams that interrupt the usual route followed by the salmon, artificial fish ladders must be built. They consist of a series of small waterfalls with still pools of water in between them (see the photo). Suppose the salmon can swim at 5.40 m/s with respect to the water. a.)What is the maximum height of the waterfall up which the salmon can swim without having to jump? b.)If a waterfall is 1.99 m high, how high must the salmon jump to get to water through which it can swim? Assume that they jump straight up. c.)If a waterfall is 1.99 m high, what initial speed must a salmon have to jump the height to get to water through which it can swim? Assume that they jump straight up.Wes stands on the roof of a building, leans over the edge, and drops a rock. Lindsay waits 1.35 s after Wes releases his rock and throws her own rock straight down at 28.0 m/s. Both rocks hit the ground simultaneously. 1) Calculate the common height from which the rocks were released. Ignore the effects of air resistance. (Express your answer to three significant figures.)
- Later during that same golf outing Marc decided to show off by trying to hit the green in one shot. He said he hit the green as the ball hung in the air for at least 15 seconds. The formula for this shot is h(x) = -16xsquared +248x. How can Marc provide proof that his shot actually hung in the air for 15 seconds?If your automobile runs out of fuel while you are driving the engine stops but you do not come to an abrupt stop.
