A0.0230kg bullet moving horizontally at500m/s embeds itself into an initially stationary 0.500 kg block. What is their velocity (in m/s) just after the collision? The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.30 kinetic coefficient of friction. Now what is its velocity (in m/s)? The bullet-embedded block now strikes and sticks to a stationary 2.00 kg block. How far (in m) does this combination travel before stopping?
A bucket filled with water exerting a force of 529N is hanging from a rope that is wound around a 0.05 m radius stationary cylinder. If cylinder does not rotate and the bucket hangs straight down, what is the magnitude of torque the bucket produce..

Suppose we have a rocket that has an acceleration of 8.92 m/s2 in the x direction. What would the acceleration in the y direction of an astronaunt be inside the rocket. Assume that the astronaunt is on Earth and that there is only an x (horizontal) a..
A capacitor has a capacitance of 2.1410-8 F. In the charging process, electrons are removed from one plate and placed on the other plate. When the potential difference among the plates is 440 V, how many electrons have been transferred?
Assume that the earth is a uniform sphere and that its path around the sun is circular. Calculate the kinetic energy that the earth has because of itsrotation about its own axis. For comparison, the total energy used in the United States in one yea..

An ac generator supplies 20 A at 220 V to a 10,000 V power line. If the step-up transformer has 110 turns in its primary coil, how many turns are in the secondary coil
Monochromatic light (λ = 570 nm) passes during two slits and onto a screen 4.0 m away. If two nearby bright fringes are separated with 14 mm, what is the slit pacing?
Two hollow metal spheres are concentric with each other. The inner sphere has a diameter of 0.40 m and is at a potential of 105 V. Find the electric energy contained in the space between the spheres
A 90° elbow is used to direct water (? = 1000 kg/m3) flow at a rate of 25 kg/s in a horizontal pipe upward. The di-ameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local ..
