A projectile is ejected from a 25-m high tower with a velocity of 40 m/s at an angle of 30 degrees to the horizontal first on Earth and then on Mars. What is the ratio of the time taken to hit the ground on Mars compared to Earth??

(Assume gravity of mars= 0.38 gravity on earth)

HOW DO I SOLVE THIS PROBLEM? need major help here! ty

- physics problem ??? -

falling a certain distnace depends on height, and g.

time to fall= sqrt(distance/g) * constant

you can work this constant out if you wish, but it will divide out .

time to fall earth/timefallMars= sqrt(.38g/g)=sqrt .38= .62

check my thinking.

You can work this out the long way if you wish...
