I've been debating with myself on a certain question. For example, Two blocks. Block A has mass M and the other Block was .5M or M/2 is pushed from rest with force F at a constant rate. (Let's say a hand pushing them for a period of time). There is friction on the surface. Block B...

thanks ehild! Yea, i forgot to add friction. It's not a problem from a book, I just wanted to make a scenario that expresses my questions. Thanks for clarifying it for me. Helps a lot!

Wait.. if we use that. acceleration is doubled because it would be a = 2F/M if the mass is 1/2M. So D for the block with the 1/2M using the same force will increase. Right?

I'm just trying to grasp the concept of work. It isn't a homework problem but if I get could feedback it would be great. Example 1: A block with mass M is pushed with a constant force F across a frictionless table and has a displacement across the table as D. My first question is that...

Homework Statement A person scuffing her feet on a wool rug on a dry day accumulates a net charge of -73 µC. How many excess electrons does this person get? Homework Equations so i did 73x10^-6 / 1.602x10^19 and i got 4.5x10^14 but one of the questions is By how much does her mass...

i see, clever. Thanks

Homework Statement An object is attached to a string L long and starting perpendicular to the ground, was moved back 60 degrees to the left. What is maximum velocity of the object achieved? I used Potential Energy = Kinetic Energy from the top to the bottom since it starts with having...

Ok, I was watching a physics lecture and there was an interesting example given Heres the Example "A rubber tire has a static coefficient of one, so at an angle of 45 degrees, the car will start to slide, which is independent of the area of the tires and mass of the car." So i did the...

i tried that but there are still two variables left. The Time and Velocity of X and Y. All that was given is the height at which the ball was thrown from, the angle it was thrown and how far it went. I can't figure out the max height to get the time of the duration or the velocities. Anyone...

Homework Statement A ball thrown from a 200 meter high cliff at an angle of 49 degrees. The ball traveled a distance of 400 meters from the base of the cliff. Find the Initial Speed of the ball. O - Ball I I I - Cliff 200 meters I I I I ............ Distance...
