An object of mass 6.8kg is attached to a spring of force constant 1870 N/m. The object is set into simple harmonic motion, with an initial velocity of = 4.3m/s and an initial displacement of = 0.16m. Calculate the maximum velocity the object has during its motion?
In a series R-L-C circuit, L=0.200 H, C=80.0 microfarads, and the voltage amplitude of the source is 240 V. What is the resonance angular frequency of the circuit
In creating his definition of horsepower, James Watt, the inventor of the steam engine, calculated the power output of a horse operating a mill to grind grain or cut wood, Calculate the power output, in hp, of a 72-kg human being
If a 62.6 kg runner dissipates a power of 60.9 W during a race, explain how fast is the person running? Assume a running step is 1.50m in length
A loop of wire (resistance = 2.0 m?) is positioned as shown with respect to a long wire which carries a current. If d = 1.0 cm, D = 6.0 cm, and L = 1.5 m, what current is induced in the loop at an instant when the current in the wire is increasing at..
What is vertical component of the acceleration

A 7.42-g bullet is moving horizontally with a velocity of +362 m/s, where the sign + indicates that it is moving to the right, find the velocity of the second block after the bullet imbeds itself
An inclined plane with friction, a massless/frictionless pulley, and two blocks, with m1 hanging and m2 resting on the plane. How do you find the acceleration
The former is on the left in contact with air and the other in contact with a liquid of index 1.4 The refractive index of the glass is 1.50. Find the positions of the foci, principal planes, and focal length of the system.Use the matrix approach
My professor today stated that if a ball was to fall a certain height, then the work done by gravity on the ball would equal the work done by the ball's equal and opposite gravitational pull. By W=F*d, this means that the earth must travel the ..
