Two workers are trying to move a heavy crate. One pushes on the crate with a force , which has a magnitude of 444 newtons (N) and is directed due west. The other pushes with a force , which has a magnitude of 107 N and is directed due north. What are (a) the magnitude and (b) direction of the resultant force + applied to the crate? Suppose that the second worker applies a force - instead of . What then are (c) the magnitude and (d) direction of the resultant force - applied to the crate? In both cases express the direction as a positive angle relative to due west. (a) Number Units (b) Number Units north of west (c) Number Units (d) Number Units south of west.
What will be the vertical position of the boat. In the frame of reference of the truck, at what angle to the vertical does the boy throw can.
A 1.35 block is attached to a spring with spring constant 14. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 50. What are The block's speed at the point where = 0.750 A.
A point charge 4.20 mu C is held fixed at the origin. A second point charge 1.60 mu C with mass of 2.80×10-4 kg is placed on the x axis, 0.280 {rm m} from the origin. The second point charge is free from rest. What is its speed when its distance f..
if a 2.5 kg ball puts 118 joules of energy in a spring with a 614 n/m constant, how far is the spring compressed.
A 3.06 kg block slides down a frictionless plane inclined 18.6' to the horizontal. If length of the plane's surface is 1.43 m, how much work is done, and by what force.
A ball is held on an incline at the height of 72 cm. it is then released so that the ball rolls down the incline. At the bottom of the incline there is a loop where the ball rolls around in. If the loop is 62 cm high at its highest point what is the ..
A skier starts from rest at the top of a hill that is inclined at 12.0° with the horizontal. The hillside is 180.0 m long, and the coefficient of friction between the snow and the skis is 0.0750. At the bottom of the hill, the snow is level and the c..
The speed of light in a transparent medium (such as glass) is less than the speed of light in a vacuum. Is this a violation of the theory of relativity.
An object consists of a ball of weight W glued to the end of a uniform bar also of weight W. if you release it from rest, with the bar horizontal.
A seed shoots out from the pod with the speed of 2.6m/s but with a direction of motion 30° below the horizontal. The seed pod is initially 1.1m above the ground.
what is the smallest value d can have before the string breaks?
Assume that, as lying on a beach near the equator of a far-off planet watching the sun set over a calm ocean, you start a stopwatch just as the top of the sun disappears.
