2. 1. B is riding in an elevator. A is on the ground at rest, and takes the following data for B: o Bis moving downward o B slows down at a rate of 1.00 m/s² over 3.00 seconds o B's speed at the start of the 3.00-s time interval is 5.00 m/s. C is in a second elevator. A takes the following data for C: C is moving upwards at a constant speed of 2.00 m/s. Make a velocity table for B showing his velocity relative to A in one column, and his velocity relative to C in a second column, at times t=Os, 1s, 2s, and 3s. Use this information to calculate the acceleration of B with respect to C. Is this acceleration constant? Why or why not?

Suppose you are in a rocket with no windows, traveling in deep space far from other objects. Without looking outside the rocket or making any contact with the outside world, explain how you could determine whether the rocket is (a) moving forward at a constant 80% of the speed of light and (b) accelerating in the forward direction.
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 rock is thrown upward from the top of a 112-foot high cliff overlooking the ocean at a speed of 96 feet per second. The rock's height above ocean can be modeled by the equation. H(t) = -16t2 +96t+112 a. Which does the rock reach the maximum height?b. What is the maximum height of the rock?
A police car traveling at 95.0 km/h is traveling west, chasing a motorist traveling at 80.0 km/h. (a) What is the velocity of the motorist relative to the police car? (b) What is the velocity of the police cat relative to the motorist? (c) If they are originally 250 m apart, in what time interval will the police car over take the motorist?
The water in a river flows uniformly at a constant speed of 2.50 m/s between parallel banks 80.0 m apart. You are to deliver a package directly across the river, but you can swim only at 1.50 m/s. (a) If you choose to minimize the time you spend in the water, in what direction should you head? (b) How far downstream will you be carried? (c) If you choose to minimize the distance downstream that the river carries you, in what direction should you head? (d) How far downstream will you be carried?
A moving beltway at an airport has a speed 1 and a length L. A woman stands on the beltway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the beltway with a speed of 2 relative to the moving beltway. (a) What time interval is required for the woman to travel the distance L? (b) What time interval is required for the man to travel this distance? (c) A second beltway is located next to the first one. It is identical to the first one but moves in the opposite direction at speed 1. Just as the man steps onto the beginning of the beltway and begins to walk at speed relative to his beltway, a child steps on the other end of the adjacent beltway. The child stands at rest relative to this second beltway. How long after stepping on the beltway does the man pass the child?
A bolt drops from the ceiling of a moving train car that is accelerating northward at a rate of 2.50 m/s2, (a) What is the acceleration of the bolt relative to the train car? (b) What is the acceleration of the bolt relative to the Earth? (c) Describe the trajectory of the bolt as seen by an observer fixed on the Earth.
A passenger in a train moving at 30 m/s passes a personstanding on a station platform at t=t'=0. Twenty secondsafter the train passes, the person on the platform determines thata bird flying along the tracks in the same direction as the trainis 800m away. Five seconds later, the bird is 850maway. Assume a constant velocity for all involved. a) Draw a coordinate system indicating the motion of bird andtrain in the grame of the observer on the platform b) What are the coordinates of the bird as determined by thepassenger? c) Find the velocity of the bird as determined by the observeron the platform and the train passenger.

You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
A person drops a ball of 100g at rest from a height of 1000m. He observes that there is air resistance (in newtons) acting on the body and it is proportional to the velocity v (in meters per second). He also notes that the limiting velocity is 245 meters per second. a) What is the velocity and distance after t seconds?b) What is the time t at which the velocity will be one-fifth of the limitingvelocity?
