In the absence of air resistance, an old textbook is launched as a projectile over level ground. Its impact point is 25 m from the launch point. Now suppose the launch speed is doubled (and the projectile is fired at the same angle above the level ground). What is the new range of the launched book

which three statements are true about all alloys?

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
