You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the empire state building. Before the state legislature votes on funding for the project, they will like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely to approve the projects unless the new elevators make the trip much faster than the old elevators. If state law mandates that elevators cannot accelerate at greater than 2.7 m/s^2 or travel faster than 17.3 m/s, what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor?
If, as is typical, each of them breathes about 500 {rm{ cm}}^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year.
The displacement of a particle moving under uniform acceleration is some function of elapsed time and acceleration. Suppose we write this displacement as: s=ka^mt^n where k is the dimensionless constant.
A 25000 kg rocket ship accelerates upwards by reason of constant 1.25MH of thrust from its engine. A simple pendulum on the ship is observed to complete 100 full swings in 75 seconds. What is the length of string.
A blob of iron sinks form the surface of earth to the center. Assume the blob does not transfer any energy to its surroundings. Assume the density of earth is uniform.
A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.30 T. The field is then adjusted so that an electron will follow a circular path of the similar radius when it is projected perpendicularly into the field with t..
If the ball is free from rest at a height of 0.67 above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? Suppose the ball is a solid sphere of radius 2.2 and mass 0.14.
The train on the right accelerates leftward at 0.82 m/s2.How far does train on the left travel before the front ends of the trains pass.
The critical angle for a special type of glass in air is 41.8. The index of refraction for water is 1.33. What is the critical angle if glass is immersed in water.
Suppose your weight has been constant, but then - after being introduced to really good chocolate - you start eating 100 extra food calories (recall, 1 food calorie is really 1kcal or 1000 calories of energy) every day without otherwise adjusting ..
If an amount of heat equal to magnitude of the work done by friction is absorbed by the crate of fruit and the fruit reaches a uniform final temperature, what is its temperature change DeltaT.
An object moves with constant acceleration 3.55 m/s2 and over a time interval reaches a final velocity of 12.8 m/s.
what volume should the balloon have after being inflated. Billiard ball A of mass mA=0.400kg moving with speed vA=1.80m/s strikes ball B, initially at rest of mass mB=0.500kg. As a result of collision, ball A is deflected off at an angle of 30.0 deg..
