A16.0g bullet is shot into a wood block at rest with a mass of 2450 g on a frictionless surface. the block moves 1.2m/s after the bullet strikes and becomes lodged in the block. find the speed of the bullet before striking the block.

The speed of the bullet before striking the block is 185 m/s.

Explanation:

Given that,

Mass of bullet = 16.0 g

Mass of wood block = 2450 g

Velocity of block = 1.2 m/s

We need to calculate the speed of the bullet before striking the block

Using equation of conservation of momentum

Hence, The speed of the bullet before striking the block is 185 m/s.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
