Question

identical water ballons are tossed from the roof of a building all with the same speed but with different angle which one has the highest speed on impact? ignore the air resistance

Answer 1

all will have the same velocity .because,consider a building with h height and let the ball be projected in an angle \[\theta \] with the horizontal and with

velocity u ,then the final velocity in every angle will be equal to
\[\sqrt{u ^{2}+2gh}\]
