marble be in the air?
a. What do you know?
b. What do you need to solve for?
c. What equation(s) will you use?
d. What is the solution to this problem?



Answer :

madankapoor10
we an assume her that marble is project with horizontal velocity=2
neglect air resistance
it falls a distance 1m
it vertical velocity initially is 0
so 1=1/2gt^2
i take g=10
then we find that t=0.2236 s
