A 3.39 kg block initially at rest is pulled to the right along a horizontal surface by a constant, horizontal force of 16 N. The coefficient of kinetic friction is 0.139. The acceleration of gravity is 9.8 m/s 2 . Find the speed of the block after it has moved 2.82 m. Answer in units of m/s
A spring k=600N/m is placed in a vertical position with its lower end supported by a horizontal surface. What is the kinetic energy of the block at the instant it has fallen 0.50m (compressing the spring0.10m)
A diving bell with interior air pressure equal to atmospheric pressure is submerged in Lake Michigan at a depth of 142.1 m. What is the magnitude of the net force on the viewing port
NASA launched a flying saucer to the top of the stratosphere. The plan was for the flying saucer to reach a height of 50 kilometer before entering the next phase of launch to the planet mars using rocket in space. Find how much time did it take fo..
If the minimum angle between the total angular momentum vector and the z axis is 32.31° (in a single-electron atom), what is the total angular momentum quantum number
A car of mass 940 kg is traveling over the top of a hill as shown in the figure below. If the hill has a radius of curvature of 34 m and the car is traveling at 13 m/s, what is the normal force among the hill and the car at the top of the hill?

A wire is formed into a circle having a diameter of10.7cm and is placed in a uniform magnetic field of3.16mT. Find the maximum torque on the wire
You can think of the sound wave as an object traveling from the bottom of the well towards the surface at a constant velocity vs = 340 m/s. At time t = 2.6 s, the sound of the stone reaches the top of the well. How deep is the well?
Figure (a) shows an element of length ds =1.00 µm in a very long straight wire carrying current. The current in that element sets up a differential magnetic field dB at points in the surrounding space
Use a computer to calculate numerically the potential energy, per ion, for an infinite two-dimensional square ionic crystal with sepa- ration a; that is, a plane of equally spaced charges of magnitude e and alternating sign
