Is that an equation?

Homework Statement Thunderstorms can have an electric field of up to 3.2 105 N/C. What is the magnitude of the electric force on an electron in such a field? Homework Equations F=k*|q1|*|q2|/d^2 The Attempt at a Solution ?

I apologize I had attemped it myself i just didn't want to write something completely wrong on here i thought it would just complicate things. Will do next time though. Thank you for the help I appreciate it. Very easy to follow. -vision

Homework Statement A 680 N student stands in the middle of a frozen pond having a radius of 6.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 2.6 kg physics textbook horizontally toward the...

Its 1634.34 N Thanks so much for the help.

Yes that was a typo, but I don't know the correct answer I have to submit to a website and it only let's me know whether my answer is correct or not and it is telling me that 1153.65 N is not correct. Are there any other approaches to this problem?

I don't know if I'm just not doing something right or what it is but, i calculated PE: PE=5768.28 J Then you told me I should plug this in for work: F=5768.28/5 F=1135.65 N unfortunately this is not the correct answer... Any ideas what it could be??

So I should find the PE of the diver at 12m? PE=49*12*9.81 PE=5768.28? The question asks to determine the average resistance force exerted on the diver by the water. So I would use W=F*D? How do I put this all together now?

Homework Statement A 49.0 kg diver steps off a 12.0 m high diving board and drops straight down into the water. If the diver comes to rest 5.0 below the surface of the water, determine the average resistance force exerted on the diver by the water. Homework Equations PE=m*g*h KE=1/2mv^2...

Thanks, i can't believe i overlooked that, wow. Thank you for the help.

Homework Statement A catcher "gives" with a baseball when catching it. If the baseball exerts a force of 511N on the glove, so that the glove is displaced 12.0 cm, how much work is done by the ball? Homework Equations W=F* \Deltax [b]3. The Attempt at a Solution [/tex] W=511*12.0?
