A0.00545-kg bullet is fired straight up at a falling wooden block that has a mass of 3.08 kg. the bullet has a speed of 720 m/s when it strikes the block. the block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. as a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a momentary halt at the top of the building. find the time t.

0.06s

Explanation:

We can solve a problem with collision using the principle of conservation of momentum, where

Where v is the velocity after the collision,

Our values are given by,

Replacing we have,

Note= Velocity block is given negative becouse V=-gt before collision, i.e, the direction changes.

For time we can use the equation of gravity, solving for t

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:
