Alead pellet of mass 10.0g is shot horizontally into a stationary wooden block of mass 100g. the pellet hits the block with an impact velocity of 250ms^–1. it embeds itself in the block and it does not emerge.
what will be the speed of the block immediately after the pellet is embedded?

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
