I got for vmin: Vsqrt((1-mu(Rg)/(V^2))/(1+mu(V^2)/(Rg))) but it keeps saying its wrong!??!?

thanks

Homework Statement A circular curve of radius R in a new highway is designed so that a car traveling at speed v can negotiate the turn safely on glare ice (zero friction). If a car travels too slowly, then it will slip toward the center of the circle. If it travels too fast, then it will...

ahh.. i still don't get it?

Homework Statement Two objects attract each other gravitationally with a force of 2.7 10-10 N when they are 0.25 m apart. Their total mass is 4.0 kg. Find their individual masses. larger mass - I kind of guessed this was 4.0 kg but don't know how to do it. smaller mass ? kg The...

alright got it! thanks!

3.13

How do I get speed, or velocity (m/s) from that? The answer is supposed to be in m/s ... I'm still confused

Is there any formula i would be able to use to solve this?

less than 25?

the tension decreases?

Homework Statement A bucket of mass 1.60 kg is whirled in a vertical circle of radius 1.00 m. At the lowest point of its motion the tension in the rope supporting the bucket is 25.0 N. (a) Find the speed of the bucket. (b) How fast must the bucket move at the top of the circle so that the...
