Time to reach highest point = u sin30°/g.
= 9.8*0.5/9.8.
= 0.5 sec.
= 9.8*0.5/9.8.
= 0.5 sec.

Thanks @Barqat Sheikh.

Correct ans is option C, 1 sec T = 2 V sin30/g.

s = v.tsin30,
s = 1/2 * gt2.
Then vtsin30 = 1/2gt2.
9.81m/s=gt since your cancel sin30 = 1/2.
t = 1sec so correct answer is c.
s = 1/2 * gt2.
Then vtsin30 = 1/2gt2.
9.81m/s=gt since your cancel sin30 = 1/2.
t = 1sec so correct answer is c.

TIME TO FLIGHT.
This is the time to complete the projectile path which is 2 x (time to reach the maximum height).
T = 2 x USinθ/g.
so the correct answer is C.

t=2 u sinθ/g is total time duration but we need highest point reach time then t=u sinθ/g.

Time to reach highest point = u sinθ/g.
Time of flight = 2 x using /g.
Horizontal range of jet = u^2 sin2θ/g.
Time of flight = 2 x using /g.
Horizontal range of jet = u^2 sin2θ/g.

Answer B or C? Tell me clearly.

Time of flight = 2usinθ/g.
As we are calculating the time taken to reach the highest point so we will divide it by 2 because in the first half time the jet will go upwards then it will drop. So the answer will be 0.5.
