Answer:

The horizontal component of its velocity of projection   = 20 \ \frac{m}{s}.

Step-by-step explanation:

As per the question a ball is thrown at an angle of theta with horizontal.

Given data are:

Horizontal range = 60 , which is denoted as S

∴ S = 60

Time of flight (t) = 3 s

As the acceleration here be = a =0

Now suppose the horizontal component of its velocity of projection is ''u''.

Using this formula,

S = ut + \frac{1}{2} at^{2}

60 = u \times 3 +\frac{1}{2} \times 0 \times 3^{2}

u=20 \ \frac{m}{s}

Hence,  the horizontal component of its velocity of projection   = 20 \ \frac{m}{s}
