    Mass attached to a rope (simple)

    AH! the mass is moving downward, but since its decelerating, its accelerating upwards, which increases the tension of the rope!

    Mass attached to a rope (simple)

    1. A 1000kg mass is lowered by a rope. If the mass is initially moving at 10m/s, and is decelerating at 1m/s2, what is the initial tension T in the rope? 2. T = mg 3. So I tried setting up T = mg, and then since it is decelerating the tension must be less than what it would be if...

    Acceleration of a mass down a decline (tricky)

    So is the acceleration (ma) in the same direction of the Tension?

    Acceleration of a mass down a decline (tricky)

    what is 2m? edit: I got the 387N by using your equation, but changed the positions of T and 2m. Can you explain the logic behind your equation. I sort of get it, but I need some clarification. I understand the force of friction and the downward force of the mass are added because they act in...

    Acceleration of a mass down a decline (tricky)

    Found this on google. The diagram in the book is identical, just ignore the hanging mass. I need to find the tension in the rope.

    Acceleration of a mass down a decline (tricky)

    The plane is inclined at a 30 degree angle. The coefficient of kinetic friction between the mass and the plane is 0.1. The mass is 100kg. If the mass is moving up the inclined plane at a velocity of 2m/s, what tension should be applied to the rope in order to make the mass reverse directions in...

    What is the frequency of the car's vibration

    Having trouble figuring out these 4 problems. I could use a walk through or an answer. thanks guys. Homework Statement 1a)When four people with a combined mass of 270 kg sit down in a car, they find that the car drops 1.00 cm lower on its springs. Then they get out of the car and bounce it up...

    Electronegativity and dipole moments

    is there a relationship between the two? its been bugging me for a while. can't find the answer.
