The diagram below shows a block of mass m=2.0\; \rm kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F_1 = 4.0\;{\rm N}, F_2 = 6.0\;{\rm N}, and F_3 = 8.0\;{\rm N} are applied to the block, initially at rest on the surface, at angles shown on the diagram. View Figure In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive).

Calculate the magnitude of the total resultant force \vec{F}_{\rm r} = \vec{F}_1+ \vec{F}_2 +\vec{F}_3 acting on the mass.

An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 860 kg traveling initially at a speed of 58.0 km/h in a distance equal to the diameter of a dime, which is 1.80 cm?

so i used the formula sum of F= (m(vf^2-vi^2))/2x.

is this wrong because i keep on getting the wrong answer. please help.

suppose you have two objects, they are both UNDISTRUCTIBLE. one of the objects is UNMOVABLE and one is UNSTOPABLE. What happens when they collide?

i was watching "castaway" and he fell down next to the fire, and i was wondering, can you get a sunburn if your exposed to a fire for too long? He was about about a foot away from a fire that was had a radius of about 2 feet and was about a foot and a half high.

A ball of diameter 31cm rolls without slipping at a linear speed of 2.8 m/s. Through how many revolutions has the ball turned as it moves a linear distance of 18 m?

Okay, how do i set this up to solve it?

I am thinking that I just take the distance and divide by the speed, and I correct in thinking this? 18m/2.8?

(Feel free to discredit me, you HAVE to, i understand) Ok if we can finally create 'anti-gravity', we could create a sheild of anti gravity, this would allow us to leave earths atmosphere without the need of rockets, then once in space we can use ion engines. Ok im 16 please dont insult me, just tell me what u think, i heard about ion engines and how they could be used once in space off a site.

a catcher "gives" with the ball when he catches a 0.113 kg baseball moving at 21.9 m/s. If he moves his glove a distance of 7.24 cm, what is the average force acting on his hand? Answer in units of kN.

What if his glove and hand move 10.1 cm? Answer in units of N.

It was stated by scientests at CERN, that if micro sized black holes were created and they didn't evaporate and one was somehow captured in the planet, it would pull in matter at a slower and slower rate. Why would not be at faster and faster rate?

OK, I know the speed of light in vacuum, and the speed sound in a given medium. But if I had (say) 1km of wire, a BIG battery, light bulb and a switch connected in series (or slightly more technical version thereof). How long after closing the switch would it take for the bulb to light? Doubtless it depends on the voltage?? But say with these old transatlantic cables there must be some measureable delay?? Just wondered? any thoughts?
