A truck weighs 3500kg you drive 0.5 km long The top of the slope you are 200 m higher in elevation than when started Assuming no friction what force has your engine exerted to drive up this slope?

7000N isn't the correct answer i think its 14000n. oplease help me figure this out

What if your light truck weighs 3500 kg you drive up a gentel slope that is 0.5 km long at the top of the slope you are 200 m higher in elevation than when you started assuming no friction what force?
The answer is 14000N. 3500(9.8)/(500/200) = 1400(9.8) = 13720 A 44% grade is not a "gentle slope."
What is the scientific meaning of the term work?
Work is force exerted over a distance. If I pushed on my car really hard and it did not move, no work was done. If my car started going without any force being exerted on it, which would be miraculous, no work would have been done.
What would happen if a car had no friction?
It would not be able to move. The push of the engine driving the car forward depends on friction between the tyres and the road. If something else started it moving, the brakes couldn't work to stop it.
Does friction change the moving direction?
It certainly can.What happens when your car is rolling along down the street and the tires on one sidehit a rain puddle in the gutter ? That side gets slowed by friction with the water, and thecar pulls toward that side.And let's not even get started on bowling balls headed down the lane.http://wiki.answers.com/Can_friction_change_the_direction_of_an_moving_object&action=editBut please note that a single object, such as ball, cannot change its direction due to friction alone. Friction is only a force that opposes motion, not a force that causes motion.
It is generally easier to push an object once it is moving than when you are getting it started this is because?
When an object is at rest, static friction is acting on it. But once it is overcome, the object moves comparatively easier due to the fact that the moving objects face kinetic friction which is always less than static friction. +++ It's not the friction you have to overcome, but its inertia, proportional to its mass. Think of an astronaut servicing something on the outside of the International Space Station. There is no friction acting on him, he is weightless and both he and spaceship are moving together through space at great speed; , but he still has mass so to move himself along the hull he still needs to push against it to overcome his inertia.
What if your truck weighs 3'500kg you drive gentle slope is 05km long at the top slope you are 200m higher in elevation when you started assuming no friction what force you engine drove up?
1400N

What if your truck weighs 3500 kg you drive up a gentle slope that is 5kg long At the top of the slope you are 200m higher in elevation then when you started with no friction what was the force?
14000N is the correct answer
What is the relationship between angle and distance?
distance and angle of elevation are closely related as the more closer you move, the half is the angle of elevation. for e.g. if you travel 30m and cover 15m then, the angle of elevation will be half of what you started with. this can be also proved by a live example as when you have the angle of elevation as 90 degree, then the distance can be zero....

Truefalse can friction slow things down?
true. Friction DOES slow things down. In fact, if there was no friction once something started moving it wouldn't be able to stop Friction can slow the things down. It's true.
What would happen when an object started moving if there is no friction?
it will go same speed forever without affecting mass and weight
What would happen if a car had no friction?
It would not be able to move. The push of the engine driving the car forward depends on friction between the tyres and the road. If something else started it moving, the brakes couldn't work to stop it.
How many Sundays are there in a period of 77 full weeks?
Assuming that this period started on a Monday then 77 Sundays.
What year did Suzanne Collins start school?
Assuming that Suzanne Collins started high school when she was 14 (1976), and again assuming that she graduated when she was 18. she would have graduated in 1980. She graduated from Alabama school of fine arts in 1980
I want 8 class book download online?
There are two main types of friction: kinetic and static. Static friction resist impending motion: the force needed to break before something starts sliding. Static friction stops acting upon the object once it starts moving. Kinetic friction resist motion: the force that is opposing existing motion, i.e. object has already started sliding.
How did Tiffany from eastenders get on the program so young?
Assuming you're talking about Martine McCutcheon - she was 18 when she started acting in Eastenders.
