Ok i have 2 questions - the first one is this:
A bullet of mass 0.01kg travelling at velocity v hits a block of wood suspended on a long string. The mass of the block is 1.00kg
(a) find the bullets velocity v (i've already done this using)
(b) to what height does the block rise after collision?
Im thinking that this is a projectile motion question
Here is the second question:
When u hammer a nail into a wall the nail exerts a force on the wall, and the wall exerts a force on the nail. How then does the nail penetrate the wall
Any help would be great!!!
