A bullet of mass Mb is fired horizontally with speed Vi at a wooden block of mass Mw resting on a frictionless table. The bullet hits the block and becomes completely embedded within it. After the bullet has come to rest within the block, the block, with the bullet in it, is traveling at speed Vf . 1)Which of the following best describes this collision? a)perfectly elastic b)partially inelastic c)perfectly inelastic 2) Which of the following quantities, if any, are...

7.HW. A bullet is fired into a block of wood sitting on a block of ice. The bullet has an initial velocity of 500m/s and a mass of 0.005kg. The wooden block has a mass of 1.2kg and is initially at rest. The bullet remains embedded in the wood afterward. (so hit and stick situation) A)Assuming that momentum is conserved, find the velocity of the block of wood and bullet after the Collision. (so momentum before = momentum. V1’=V2'=V') B)What...

1. A 0.012 kg bullet is fired horizontally into a 0.1 kg wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant k= 150 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 0.8 meter and comes to complete stop, what was the speed of the bullet at impact with the block? -www-
A 9.0 g bullet is fired into a 8.0 kg wood block that is at rest...
A 9.0 g bullet is fired into a 8.0 kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0 cm across the table. The coefficient of kinetic friction for wood sliding on wood is 0.20. What was the speed of the bullet?
A 9.0 g bullet is fired into a 11 kg wood block that is at rest...
A 9.0 g bullet is fired into a 11 kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0 cm across the table. The coefficient of kinetic friction for wood sliding on wood is 0.20. Whats the Speed of the bullet?
A 10 g bullet is fired into a 10 kg wood block that is at rest...
A 10 g bullet is fired into a 10 kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0 cm across the table. The coefficient of kinetic friction for wood sliding on wood is 0.20.What was the speed of the bullet?
A 910 gram bullet is fired into a 30.0 kg block of 293 K ballistic gel....
A 910 gram bullet is fired into a 30.0 kg block of 293 K ballistic gel. The bullet and the block then combine and slide 1.06 m across the floor (uk=0.20) to a stop where the block of gel reaches a temperature of 302 K, Estimate the speed of the projectile before it hit the block? Please show work!!
An 7.71g bullet is fired into a 320g block that is initially at rest at the...
An 7.71g bullet is fired into a 320g block that is initially at rest at the edge of a table of h = 1.03 m height (see the figure below). The bullet remains in the block, and after the impact the block lands d = 2.19 m from the bottom of the table. Determine the initial speed of the bullet. Submit Answer Incorrect.

A 12g bullet is fired into a 12kg wood block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0cm across the table. The coefficient of kinetic friction for wood sliding on wood is 0.20. awnser should be in m/s
A 12.0-g bullet is fired horizontally into a 115-g wooden block that is initially at rest...
A 12.0-g bullet is fired horizontally into a 115-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 146 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 88.5 cm, what was the speed of the bullet at impact with the block?
