Expert Answer:

lowest speed of projectile motion is when the object reaches the maximum height.
 
At the point of maximum height vertical component of velocity is zero and the particle has only horizontal component.
 
Hence lowest speed of the object in projectile motion is  ( 5 cos30 ) m/s  , i.e. 5×√3/2 = 4.33 m/s
