We know that momentum=mass×velocity..If a pebble of mass ...

The density of a pebble is much more compared to a ball of crushed paper. I is pretty hard to make a paper ball the same size of a pebble so it would be unreasonable to assume that they're the same size. The smaller area of impact would allow the pebble to hit an area in a concentrated spot so it would hurt much more when you are hit by a pebble.
