Suppose Arturo is standing on a spring bathroom scale in an elevator, which is at rest, on the 15th floor. What is his acceleration? What forces are acting on him? What is the reading (in Newtons) on the bathroom scale if he has a mass of 150 kg? (Draw it out and Label it) Now imagine disaster - the rope holding the elevator snaps, there are no safety features, and the elevator plunges down the shaft in free fall. Herrera...

Service Quality at the Remington Hotel Day One Madeline Lewis had recently transferred to the Remington Hotel to improve the level of service quality. She had been with the company for five years and had been quite successful in improving the level of service quality at the two previous hotels to which she had been assigned. Madeline knew that the Remington was going to be a real challenge. The mix of business was 60 percent individual transient guests and 40...

A 5.0-kg carl (cart 1) rolling cast on a level, frictionless track at 18.0 m/s, collides with a stationary 4.0-kg cart (cart 2). After the collision, cart 1 is still rolling cast, but now at a speed of 2.0 m/s. (a) Assuming the total momentum of the two-cart system is conserved, calculate the final velocity of the second cart. (b) Before the collision, the system's total kinetic energy was 810 J. Calculate the total kinetic energy of the two-cart system...

QUESTION 15 Now let's use the concept of work using the classic story. Suppose David is spinning his sling at angular velocity w = 2 * 10 sec-1, which corresponds to 10 revolutions per second. The centrifugal force due to the rotation is given by the expression mw'r, where r is the distance from the center of rotation and is the mass of the stone begin slung....

There was a car accident. Someone stopped and the person
behind them rear ended them. The car that stopped slid away about
30 feet and the car that did the rear ending stopped right about
where the collision happened. Was this a perfectly inelastic
collision? Why or why not?
A perfectly elastic collision is one in which kinetic
energy is conserved. How exactly is kinetic energy not conserved
though? Sometime KE can be used up compressing/bending things and
making heat,...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how
