Q. Two blocks are sliding across a table pushed by a force F from the left equal to 23 N. The force of friction from the table on m1 is 4 N and the force of friction on m2 is 12 N. m1 = 2 kg and m2 = 6 kg. a) What is the magnitude acceleration of the entire system? I figured this part...

A uniform chain of length 8.00m initially lies stretched out on a horizontal table. a) If the coefficient of static friction between the chain and the table is 0.600, show that the chain will begin to slide off the table if at least 3.00m of it hangs over the edge of the table. b)...

Can someone please help me with this problem? I've tried a few different things but none of them worked... The weight of the block in the drawing is 99.0 N. The coefficient of static friction between the block and the vertical wall is 0.510. (a) What minimum force F is required to prevent...

Hello, I've just joined this forum in hopes of finding some help to my physics problems. I usually can find out what to do by myself, but this problem seems to be requiring some advanced concepts...or it maybe is so that I'm just not using my noodle. A car is sliding down an inclined plane...

Please Help, I've asked two physics majors for help now and they can't tell me can anyone be of assistance? A block with a mass m=16.5 slides down an inclined plane with a slope angle of 32.7 degress with a constant velocity. It is then projected up the same plane with an initial speed of...

Greetings fellow physicists! I am stuck on a problem, please help. The situation is a block on a rough incline (trainglular block), the incline itself is on a frictionless table. A horizontal force is applied to the incline. The question is to find the minimum horizontal force needed so that...

A block lies on a smooth plane tilted at an angel 25.5 degrees to the horizontal with coefficient of kinetic friction = 0.17. What is the acceleration of the block as it slides down?

An object slides down an inclined plane of angle 30 degrees and of incline length 4m. If the initial speed of the object is 5m/s directed down the incline, what is the speed at the bottom? Neglect friction. I used Kinitial+Uinitial=Kfinal+Ufinal. I got 2gh+5^2=v^2, but when I solve for v...

A 10 kg block slides from rest down a 5m long ramp. If the coefficient of friction between the block and the ramp is 0.4, what is the final velocity of the block when it reaches the botton of the ramp? I set this into two Fnet equations, x and y. I then solved for the acceleration in x...

Imagine an initially stationary block is placed at some height on a frictionless ramp. The ramp has several hills and valleys in it. Assume the block never flies off the ramp, the hills have identical circular tops, and the hills are of progressively greater heights, all shorter than the height...

i'm trying to learn this stuff on my own so please bear with me. here's the problem: you have two mass, a 10kg on a frictionless 35 degree inclined plane, which is attached to 20kg mass via a pulley cord to hang vertically. Whats the aceleration? Solution: for the box hanging freely...

I'd appreciate a tip here. A 10 kg object on a horizontal, unsmooth table is pushed to the right so as to have an intial velocity of 20 m/s. It comes to rest 5 seconds later, during which time its acceleration (deceleration?) was constant. I've already figured out the acceleration (4 m/s^2)...

I'd like to make sure I understand it. It reads... "Two objects, A and B, are placed in contact with each other on a horizontal, frictionless surface. Object A weighs 1.5kg, and B weighs 2.5kg. If a force of 8.0N is exerted on the surface of object A in contact with B AND on the opposite...

Ok, I have a maths question. This is a little different because I don't want the answer, I want the formula so I can work out the answer (and future answers) myself. lol it's not very good self-learning with a book that doesn't tell you much. Anyway here is the question. A solid uniform cube...

when you close those sliding doors really hard the door will eventually bounce back out about half way where you have pushed the door. is it because every force has an opposite side of force ? for example when we put the book on the table, the gravity force is pulling the book down but the...

Ok, I have been going over this problem and the answer I got just doesn't make sense...help! It's a really easy problem (apparently) but the answer that I keep getting doesn't make sense to me...please let me know what I'm doing wrong or forgetting or whatever... I thought it'd be...
