The time for the projectile to land is 4.41 seconds.

Explanation:

The total time taken to reach ground is the TIME OF FLIGHT.
Time of flight #T=(2usintheta)//g#
We consider acceleration due to the gravity #'g'=9.8m//s^2#.
Substituting the numericals we get
#T= [2xx25m//sxxsin(2pi//3)]//9.8m//s^2#.
#:.T=4.41 seconds#.
