A ballistics test involves firing a 10.0g bullet horizontally into a 1.50kg wood block that is initially at rest. The bullet bec
omes lodged in the block, and you determine that they move together at a speed of 5.00m/s. With this information, determine the velocity of the bullet before it entered the block.
Work equals force × displacement (distance between initial point and end point is displacement) if u follow this it becomes work = 50 × 2 which is equal to 100
