A 3-gram bullet is fired horizontally into a 10-kilogram block of wood suspended by a rope from the ceiling. The velocity of the bullet just before the collision is 750 m/s. The block swings in an arc, rising a height h from its lowest position. What is h in millimeters? (Hint: You must apply conservation of momentum to the collision to find out how fast the block+bullet move together before you can use conservation of Energy to find h.)

The height raised by the blcok is 2.5 mm.

Explanation:

Given that,

Mass of the bullet,

Initial speed of the bullet,

Mass of the block of wood,

It was at rest, initial speed of the blockof wood,

The block swings in an arc, rising a height h from its lowest position. The momentum remains consered. Let V is the velocity of the block +bullet system together. So,

Now using the conservation of energy to find the height h raised by the blck. So,

So, the height raised by the blcok is 2.5 mm.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
