    Why Does the Block Not Reach the Expected Distance on the Incline?

    Gun Shoots Block Up Incline! 1. A block of mass m is placed in a smooth-bored spring gun at the bottom of the incline so that it compresses the spring by an amount x. The spring has spring constant . The incline makes an angle (theta) with the horizontal and the coefficient of kinetic friction...

    Tension/ Force problem; How should I look at this?

    No, btween a and b m=.4; so T= 1.5N Thanks, I understand now! :-)

    Tension/ Force problem; How should I look at this?

    Ok so a= 3.75 m/s^2; From this: F= 1.2*3.75; F=4.5N; T=.8*3.75; T=3N ?

    Tension/ Force problem; How should I look at this?

    1. Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F. The magnitude of the tension in the string between blocks B and C is T= 3.00N. Assume that each block has mass m= 0.400kg . [a]--------[c]---->F What is...

    Is 1.875×10^8 m/s² the Correct Acceleration for the Electron in the TV Tube?

    1. An electron of mass 9.11×10^−31 kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is a distance 1.20 cm away. It reaches the grid with a speed of 4.50×10^6 m/s. The accelerating force is constant. Find the...
