(a) the initial speed of the grasshopper

Let us consider vertical component of velocity,

where,as it reaches max height, its final velocity will be zero,

Initial velocity =v sin 50,

distance s = 6.74 cm = 0.0674 m

Acceleration , a = g =

Substituting given data in above equation,

v = 1.5 m/s

Therefore, the initial velocity of the grasshopper is 1.5 m/s.
