Sam and Becky each move 10 boxes. Sam moved the boxes in 30 minutes, while Becky moved them in 20 minutes. Assuming the boxes required the same amount of force to move, and they were all moved the same distance, which of the following is true?
1.Becky did more work than Sam, because it was done faster
2. Sam did more work than Becky, because it took longer
3. Becky had more power than Sam but did not do more work
4. Sam had more power than Becky but did not do more work
Homework Answers
Answer #1
Sam and Becky apply the same amount of force on each boxes in moving the same distance which means workdone by same and becky is same but their rate of doing work is different , Becky has more power than sam because Becky did the same amount of work as Sam does in a less time.

Sam is a business executive who flies often in connection with
work. After the September, 2001 terrorists' destruction in New York
and Washington, Sam flew less frequently. In response to the
attacks, new federal regulations made the federal government
responsible for all airport security personnel. In most cases,
including at Sam's home airport, the government met the obligation
by hiring private contractors to provide the security services.
These firms were heavily regulated and controlled by the
government. Also, in the...

1. For an object moving in uniform circular motion, does the
centripetal force do work on the object?
A.
Yes, because work is force times distance and the object is
moving from the force.
B.
No, because the force is always perpendicular to the object's
displacement.
C.
No, because the displacement of the object is zero.
D.
Yes, because the object is moving.

to solving
1) A 30 g steel ball is released from rest and falls vertically
into a steel plate. The ball strikes the plate and is in contact
with it for 0.5 ms. The ball rebounds elasticity, and returns to
its original height. The time interval for a round trip is 4.00 s.
In this situation, the average force exerted on the ball during
contact wth the plate is closest to:...

Mad Vlad Microbrewery
Mad Vlad Microbrewery is owned by Sam and Sadie, craft brewers.
They began producing their special brand of craft beer in
Transylvania County. When they were getting started, Mad Vlad was
produced in a small facility owned by a family member with
production primarily sold in their hometown. Over time, as the
craft beer industry grew, and microbreweries were in increasing
demand, Sam and Sadie began to expand in response to demand for
their product.

Case:
Raheel & Co. was the only manufacturer of shuttle box for
power loom in Pakistan and has monopoly for the last 60 years. The
company was founded in 1958, and established the market of manual
loom shuttle boxes. With the passage of time, they started to make
electronic and later smart shuttle boxes which were controlled by
computer. These shuttle boxes are very complicated their technology
is inimitable. Back in 1998, Mr. Raheel Ashraf died with cancer and

Suppose the two cars had rubber
bumpers in the front and back – similar to the bumper cars children
(of all ages!) ride at amusement parks. Also, suppose that the cars
are sturdy enough that the metal they are made of does not bend
during the collision. In this case, the cars would undergo a
perfectly elastic collision. Assume just like in the first
collision question that the SUV (initially moving to the right)
collides into the stationary smart car....
