The force exerted by the wind on the sails of a sailboat is Fsail = 400 N north. The water exerts a force of Fkeel = 220 N east. If the boat (including its crew) has a mass of 320 kg, what are the
The energy density inside a certain capacitor is 8 J/m^3. What is the magnitude of the electric ?eld inside the capacitor?
The total electric flux from a cubical box 26.0 cm on a side is -1.90 × 103 N·m2/C. What charge is enclosed by the box?
If sunflower blossoms always pointed straight up (as daisies do), what power would the sunflower disk described in part "a" be receiving at 5:00 P.M.?
Imagine a "free" electron and a "free" proton held midway between the plates of a charged parallel plate capacitor. When released, how do their accelerations and directions travel compare?
Draw the force vectors with their tails at the origin of the coordinate system. The orientation of your vectors will be graded. The exact lengths of your vectors will not be graded but the relative
A cart (with wheels) sits on a horizontal table. The front of the cart is a vertical wall, with mass M = 0.908 kg held against the wall. You want to push the cart forward with an acceleration of ma
Find f, the magnitude of the force of static friction exerted by the wall on the block.
Find F, the magnitude of the force, exerted downward along the handle, that will cause the mop to slide across the floor without acceleration.
A block of ice of mass m slides down an incline that makes an angle θ = 28.6o with the horizontal. In trial 1 there is no friction; the block starts at rest and takes time t to reach the bott
A sled of mass M = 384 kg is being pulled along a horizontal surface by a massless rope that makes an angle of θ = 19.1o up from the horizontal. The rope is pulled with a force of magnitude F
A box of mass m = 5.95 kg sits on a frictionless, horizontal table. A heavy rope is attached to the box, and it is pulled horizontally by a force of magnitude F = 64.2 N. (You can ignore any sag in
An 8.00 {kg} point mass and a 15.0 {kg} point mass are held in place 50.0 {cm} apart. A particle of mass m is released from a point between the two masses 17.0 {cm} from the 8.00 {kg} mass along th
