A .025 kg bullet is moving at 350 m/s when it hits and then passes through a 7 kg block of wood. After the bullet passes through the block the bullet slows to 60 m/s. What is the final velocity of the block of wood after the bullet passes through? (No mass is lost)

The final velocity of the wooden block is equal to

Explanation:

Given that mass of bullet =

                Mass of wood =

               Initial velocity of bullet =

              Final velocity of bullet =

               Initial velocity of wood = o

               Final velocity of wood =

   Here momentum is conserved so initial momentum = final momentum

            .

    Upon substituting these values in above equation , we get

        .

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
