A bullet with a mass of .06 kg hits a 5.0 kg block with an initialspeed of 225 m/s. The block is connected to a spring. The friction between the block and the table is negligible. Uponimpact the bullet bounces back from the box with a speed of 75m/s.
a) Calculate the speed of the block right after the collision?
b) As a result of the collision the spring compresses to a maximumof .20 m. Find the spring constant?
c) Find the inelastic energy loss during the collison?
A 30 cm spring is compressed to 2 cm. a force of 200 N was used to do this. How much potential energy is stored in the spring
A boat moves through the water with two forces acting on it. One is a 1800 N forward push by the water on the propeller, What will its velocity be at the end of that time
calculate the average acceleration in m/s^2 (meter per second square), using a coordinate system with the X axis in the direction of the car's original motion and the Y axis toward the side of the road to which the car skids.
The de Broglie wavelength is lambda = h/p, but the momentum of a relativistic particle is not mv. what is the electron's de Broglie wavelength
Consider the driven, damped harmonic oscillaror discussed. (a) Calculate the power dissipated by the damping force. (b) Calculate the average power loss, using the fact that the average of sin2( ?t+?) over a cycle is one-half.
A circular loop of wire is in the plane of the paper. The south pole of a bar magnet is being moved from a position in front of the paper in a direction away from the center of the loop. Which is the direction of the induced current in the loop?
a given capacitor is connected to a 12.0 v battery and when fully charged stores 2.58 x 10-6 j of energy. if the
Giancoli, page 30 --when they say that x-xo increases with the square of the initial speed. Why do they say square of initial speed only, what about square of final speed? And why do they ignore that the distance also decreases by a factor of 2.
Four Point charges have equl magnitudes, three are positiveand one is negative. Calculate the ratio of largest to smallest net force
capacitors wont hold a charge indefinitely as time goes on charge gradually migrates from the positive to the negative
A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 N on him. What force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg
