A small wooden block with mass 0.775 kg is suspended from the lower end of a light cord that is 1.52 m long. The block is initially at rest. A bullet with mass 0.0136 kg is fired at the block with a horizontal velocity of 375 m/s . The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. The block and bullet rise so that the cord...

6) A 0.200 kg hockey puck is launched up a metal ramp that is inclined at a 30.0° angle. The coefficients of static and kinetic friction between the hockey puck and the metal ramp are = 0.40 and 14 = 0.30, respectively. The puck's initial speed is 63 m/s. What vertical height does the puck reach above its starting point? Answer: units

A small wooden block with mass 0.775 kg is suspended from the lower end of a light cord that is 1.74 m long. The block is initially at rest. A bullet with mass 0.0112 kg is fired at the block with a horizontal velocity v0. The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. When the block has risen a vertical height of 0.800 m ,...

Suppose the hockey puck in the problem above is placed on a different ramp that is not frictionless, but instead has coefficients of static and kinetic friction equal to 0.80 and 0.76, respectively. (a) At what angle would this ramp have to be placed in order for the puck to begin to slide down the ramp? (b) What would be the acceleration of the puck as it slides down this ramp set at the angle calculated in (a) ? (c)...

A small wooden block with mass 1.00 kg is suspended from the lower end of a light cord that is 1.50 m long. The block is initially at rest. A bullet with mass 20.0 gr is fired at the block with a horizontal velocity vo. The bullet stikes the block and become embeded in it. After the collision the combined object swings on the end of the cord. When the block has risen a vertical height of 0.500 m, the...

12. (20 points) A 5 gram bullet is fired at a wood block that is supported at rest on a smooth incline plane (no friction) at an angle of theta above the horizontal. The bullet is fired with a speed of 500 m/s, but then impacts and passes straight through the wood block, coming out the other side with a speed of 400 m/s. As a result of the collision, the wood block slides up the ramp 5 cm from...

Chapter 07, Problem 34 Chalkboard Video The drawing shows a
collision between two pucks on an air-hockey table. Puck A has a
mass of 0.0170 kg and is moving along the x axis with a velocity of
+4.65 m/s. It makes a collision with puck B, which has a mass of
0.0340 kg and is initially at rest. The collision is not head-on.
After the collision, the two pucks fly apart with the angles shown
in the drawing . Find...
