It is 2055 and Elon Musk has just completed his new colony on the tiny planet Zook. He is standing on a high cliff on Zook, and wishes to determine the height of a cliff. Therefore, he drops a rock off the cliff and it falls for 5 seconds. Elon Musk knows that gravitational acceleration on Zook is 2 (m/s)/s. a) EXPLAIN how you would use the How fast method to determine the speed of the rock when it reaches the ground as well as the average speed of the rock during this time. Give the speed and average speed of the rock. EXPLAIN how you would use the How-far method to determine height of the cliff. Give the height of the cliff.

An observer sitting on a park bench watches a person walking behind a runner. Figure P4.72A is the motion diagram representing what this observer sees. To better reveal the changing distance between runner and walker, five observations (A through E) are shown on five separate lines in Figure P4.72B. To the observer on the bench, both the runner and the walker move to the right, and the gap between them widens. Draw the motion diagram of the runner from the reference frame of the walker.

An experimentalist in a laboratory finds that a particle has a helical path. The position of this particle in the laboratory frame is given by r(t)=Rcost+Rsint+vztk where R, vz, and are constants. A moving frame has velocity (vM)L=vzk relative to the laboratory frame. a. What is the path of the particle in the moving frame? b. What is the velocity of the particle as a function of time relative to the moving frame? c. What is the acceleration of the particle in each frame? d. How should the acceleration in each frame be related? Does your answer to part (c) make sense? Explain.
Consider the Earth and the Moon as a two-particle system. a. Find an expression for the gravitational field g of this two-particle system as a function of the distance r from the center of the Earth.

Professor Wells (from the Computer Science department) is going to ride the Argus CycleRace in Cape Town this weekend. The race is 108 km long.(a) Prof. Wells is comfortable riding at an average speed of 25 km/h, but he would like to ride the race in under 4 hours. What average speed will he need to ride in order tofinish the race in 4 hours?(b) During the race, Prof. Wells finds that he rides down a 15 km long hill at an average (9)speed of 45 km/h. This downhill is followed immediately by a 15 km long uphill ride.With what average speed will Prof. Wells need to ride up the hill to maintain anaverage speed of 30 km/h over the 30 km stretch of road?
In his 1865 science fiction novel From the Earth to the Moon, Jules Verne described how three astronauts are shot to the Moon by means of a huge gun. According to Verne, the aluminum capsule containing the astronauts is accelerated by ignition of nitrocellulose to a speed of 11 km/s along the gun barrel’s length of 220 m. (a) In g units, what is the average acceleration of the capsule and astronauts in the gun barrel? (b) Is that acceleration tolerable or deadly to the astronauts? A modern version of such gun-launched spacecraft (although without passengers) has been proposed. In this modern version, called the SHARP (Super High Altitude Research Project) gun, ignition of methane and air shoves a piston along the gun’s tube, compressing hydrogen gas that then launches a rocket. During this launch, the rocket moves 3.5 km and reaches a speed of 7.0 km/s. Once launched, the rocket can be fired to gain additional speed. (c) In g units, what would be the average acceleration of the rocket…
A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000 km. Suppose it accelerates at 20.0 m/s2 for the first 15.0 min. of the trip, then travels at constant speed until the last 15.0 min. when it accelerates at –20 m/s2, just coming to rest as it reaches the moon. (a) What is the maximum speed attained? (b) What fraction of the total distance is traveled at constant speed? (c) What total time is required for the trip?
At noon, Fred is driving south on Highway 1, 50 miles north of its intersection with Highway 2. He is traveling at 40 miles per hour. At noon, Jill is driving west on Highway 2 through its intersection with Highway 1. She is traveling at 30 miles per hour. (a) When will Fred reach the intersection with Highway 2? (b) How far apart will the two cars be at that time? (c) When will the two cars be closest to each other, “as the crow flies”? (d) How far apart will they be at that time?
Suppose a spaceship starts from rest from Space Station Alpha floating in deep space and accelerates at a constant rate of (relative to the station) for 1.0 Ms (≈ 12 days), decelerates for the same amount of time to arrive at rest at Space Station Beta (which floats at rest relative to Alpha), and then repeats the same acceleration and deceleration processes in the opposite direction to get back to space station Alpha. (a) Find the spaceship’s top speed. Is it small compared to the speed of light? (b) About how much less time has elapsed on the spaceship compared to clocks on Station Alpha? (Hint: Divide the trip into four pieces, and use the binomial approximation to convert the integral to two simpler integrals for each piece.
