An ideal spring with a spring constant of 25.0 N/m is suspended vertically. A 1.00 kg object is attached to the unstretched spring and released. It then performs oscillations in the form of simple harmonic motions. Determine the magnitude of the oscillations.
A cargo plane is flying horizontally at an altitude of 11.5 km with the speed of 820 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance.)
There is a uniform magnetic field present, given by B=0.003i + 0.004j + 0.002k, where i, j, k are the unit vectors along the cartesian coordinate axes') in units of Tesla. Compute the y-component of the magnetic force acting on a segment of wire ..
