Ezy velocity questions! Please help me // I am desperate!
a)How long does it take an object to fall from a height of 20 m to reach the ground?
b)if an object is launched horizontally from a height of 20 m with a velocity of 2/m/s where will it hit the ground?
we can use the velocity /a cceraltion forumulas
is part a correct?? i think 20/ 9.8 m/s because its falling vertically which = 2.04 seconds
but part b I am not sure?
