A 3.0 kg block, initially in motion, is pushed along a horizontal floor by a force F of magnitude 18 N at an angle = 45° with the horizontal. The coefficient of kinetic friction between the block and floor is 0.25. (Assume the positive direction is to the right.) Calculate the...

Re: Physics - drwls #2
Posted by winterWX on Monday, March 19, 2007 at 11:54pm. A small block of mass m = 4.0 kg can slide along the frictionless loop-the-loop. The block is released from rest at point P, at height h = 23R above the bottom of the loop (R is the radius of the loop). Express your ...

a) yes, but I wonder how you got the time to max height. b) I have no idea what "right before...returns to ground" means. The wording is very poor. In physics, we consider gravity returning the projectile to ground starting at launch and working until it strikes the ground.

I've been doing extra questions for physics, but these four are still giving me trouble. Please help me solve them, including Free Body Diagrams if possible. 1. If a curve with a radius of 60m is properly banked for a car traveling at 60km/hr, what must the coefficient of ...

Physics Help Please?
I counted over 20 questions. That is a lot more than "a few". Many are easy multiple choice questions for which you should have some idea of the answer if you expect to pass the course, or have learned any physics at all. Someone will be glad to critique your efforts. None of ...

Hi guys, Im a bit stumped on how to solve an online physics homework problem and it's really bothering me. I have no idea how to come up with the angles or even attempt the problem and neither do my friends. We'd all really appreciate it if someone could help us. Many Thanks, ...

A 2.0 kg mass starts from rest and slides down an inclined plane 8.0 X 10^-1 m long in .50s. what net force is acting on the mass along the incline. I have no idea how to do this I don't know why they just didn't say .8m the back of the book says 13 N down the incline I can ...

A 5.0 kg bucket of water is raised form a well by a rope. If the upward acceleratiopn of the bucket is 3.0 m/s^2 find the force exerted by the rope on the bucket of water what exactly do i do here? 3.0 m/s^2 upward? is this the Fn? I have no idea how to do this problem...

The professor gave us no background material or explanations for any of these questions. 1. Imagine that molecules of H20 are stacked up in a cubic array, like a large number of cubical boxes. Each water molecule is taken to be at the center of each cube in this array. Let the...

The mass of the stick where M resides is 30g, centered at distance 15. The mass of the stick where m resides is 70, centered at distance 35 Adding up all the mass*distance values, they must balance on both sides of the fulcrum. 30(15) + 200(20) = 70(35) + 50(d) 450 + 4000 = ...
