Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.9e10^6 N, one at an angle 12.0 degrees west of north, and the other at an angle 12.0 degrees east of north, as they pull the tanker a distance 0.700 km toward the north. What is the total work done by the two tugboats on the supertanker? Express your answer in joules.
Solution Preview
F1 is the force at the angle 12.0 degrees west of north, F2 is the force at the angle 12.0 degrees east of north, F1 and ...
Solution Summary
Combination of two forces should direct to the North.
A 90g bullet is fired from a rifle having a barrel 0.690m long. Assuming the origin is placed the bullet begins to move, the force (in newtons) exerted on the bullet by the expanding gas is 1000 + 6000x- 35000x*x where x is in meters.
a) Determine theworkdone by the gas on the bullet as the bullet travels the length of the
The only force acting on a 2.4 kg body as it moves along the x axis varies as shown in Fig. 7-33 (attached). The velocity of the body at x = 0 is 4.0 m/s.
(a) What is the kinetic energy of the body at x = 3.0 m?
(b) At what value of x will the body have a kinetic energy of 8.0 J?
(c) What is the maximum kinetic energy attai
What are standardized work instructions? Comment on some of the characteristics that effective standardized work instructions have and the benefits that organizations can enjoy by implementing them after close of a project. Provide an example.
Assume that the earth and the moon have circular orbits (which is almost true) and that the periods of their orbits are 365 days and 28.0 days, respectively
How much work does the earth do on the moon in one day?
W(earth)= ? J
How much work does the sun do on the earth in one month?
W(sun)= ?J
Hello,
I have to write a paper that highlights one key feature of the European work environment and how it differs from the U.S. environment. I just looking for a couple hundred words to get started and I'll finish the rest.
An 80 kg jogger starts from rest and runs up the hill into a stiff breeze. At the top of the hill the joggers body has done a work of 1.8 X 10^4 J, air resistance has donework of 4420J, and the joggers speed is 3.5 m/s.
(1) Is theworkdone by the joggers body positive or negative? I this workdone by a conservative or non-c
