A2.50-g bullet, traveling at a speed of 425 m/s, strikes the wooden block of a ballistic pendulum, such as that in the picture. the block has a mass of 215 g. (a) find the speed of the bullet/block combination immediately after the collision. (b) how high does the combination rise above its initial position?

4.88505 m/s

1.21629 m

Explanation:

= Mass of bullet = 2.5 g

= Mass of block = 215 g

= Velocity of bullet = 425 m/s

= Velocity of block

Here, the linear momentum is conserved

The speed of the combination of mass is 4.88505 m/s

The energy in the system is conserved

The maximum height the combined mass will reach is 1.21629 m
