The figure below shows a bullet of mass 190 g traveling horizontally towards the east with speed 405 m/s, which strikes a block of mass 3.0 kg that is initially at rest on a frictionless table.
After striking the block, the bullet is embedded in the block and the block and the bullet move together as one unit.
(a)
What are the magnitude (in m/s) and direction of the velocity of the block/bullet combination immediately after the impact?
magnitude
Incorrect: Your answer is incorrect.
m/s
direction
Correct: Your answer is correct.
(b)
What are the magnitude (in N · s) and direction of the impulse by the block on the bullet?
magnitude
Incorrect: Your answer is incorrect.
N · s
direction
Correct: Your answer is correct.
(c)
What are the magnitude (in N · s) and direction of the impulse from the bullet on the block?
magnitude N · s
direction
Correct: Your answer is correct.
(d)
If it took 3 ms for the bullet to change the speed from 405 m/s to the final speed after impact, what is the average force (in N) between the block and the bullet during this time? (Enter the magnitude.)
N

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
