Problem 63P

A grasshopper leaps into the air from the edge of a vertical cliff, as shown in Fig. P3.63. Use information from the figure to find (a) the initial speed of the grasshopper and (b) the height of the cliff. Step-by-Step Solution:

Solution 63P

Step 1 of 5:

(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.
