gravity will be at a point along its diagonal ___ from vertex V
4 x 10^-9 C if a force of 9.3 x 10^-4 N
If the quality factor of an underdamped harmonic oscillator of frequency 512 be 8×104 calculate the time in which its energy is reduced to 1/eth of its energy in the absence of damping. How many oscillations does the oscillator make in this time?
The force on bullet is given by the formula F=580-(1.8x10^5)t over the time interval t=0 to t=3x10^-3s. F is newtons. Sketch a graph F vs t for t=0 to t=3x10^-3
If the quality factor of an underdamped harmonic oscillator of frequency 512 be 8×104 calculate the time in which its energy is reduced to 1/eth of its energy in the absence of damping. How many oscillations does the oscillator make in this time?
A simple pendulum is found to vibrate 50 times within 200s. When 1.5m of its length is reduced to a certain length, it vibrates 50 times in 175s. Find the original length of the pendulum.
The center of mass of a pitched baseball or radius 1.65 cm moves at 28.2 m/s. The ball spins about an axis through its center of mass with an angular speed of 69.1 rad/s. Calculate the ratio of the rotational energy to the translational kinetic energy. Treat the ball as a uniform sphere.
