The time is

#### Explanation:

Resolving in the vertical direction

The initial velocity is

The time to reach the greatest height is

Applying the equation of motion

The time is

The time taken to land is twice the time to reach the greatest height

#### Explanation:

*Here you actually asked about the wandering period of the projectile.*

**The initial velocity, #v_0=15 ms^(-1)#**

**The throwing angle of the projectile,θ= #pi/6=30@# **

The wandering period of the projectile,

**we know that,**
