A 52.0 kg mass attached to a spring oscillates with an amplitude of 2.25 m. The total mechanical energy of the system is 410 J. Find the position of the mass when its speed is 2.00 m/s.
By how much horizontal force would you need to apply to a 3.0 N plastic calculator to start it moving from rest? How much horizontal force would you need to keep it moving?
A 2.30-?F capacitor is fully charged by being connected to a 6.0-V battery, Calculate the maximum current in the inductor, Calculate the frequency of oscillation of the LC circuit
From point B, the ball was in the air 2.0 seconds and traveled a horizontial distance of 16.2 meters before hitting the ground. Illustrate with what velocity did the ball leave her hand at point B?
A mass m = 90 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 18.8 m and finally the flat straight section at the same height as the center of the loop (18.8 m off the ground). Because the mass would not..
define the magnitude of the external field. The Speed time graph of a particle moving along a fixed direction is shown below. Obtain the distance travelled by the particle between t=0 and t=10s. What is the average of the particle over this interva..
An object with a mass of 27.0 g displaces 845.0 ml of water when it is completely immersed. What is the buoyant force on the mass
Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2. Suppose that the blocks accelerate with an acceleration of magnitude a = 0.550 m/s^2 and that coefficient of kinetic friction b..
