Question

A cricket player can throw a ball with an initial speed of 30 m / s. What is the maximum range of the player can throw the ball? Neglect air resistance. [Take, . g=10 m / s 2] (A) 100 m (B) 90 m (C) 80 m (D) 90 √2 m

Maximum range occurs, when angle of throw θ=45° Also, range maximum =.(u2 sin 2 θ/g)|θ=45° =(u2/g)=(900/10)=90 m

Q. A cricket player can throw a ball with an initial speed of $30 m / s$ . What is the maximum range of the player can throw the ball? Neglect air resistance. [Take, $g = 10 m / s^{2}]$

100 m

90 m

80 m

$902 m$

Maximum range occurs, when angle of throw $θ = 4 5^{\circ}$
Also, range maximum $= \frac{u ^{2} s i n 2 θ}{g} ∣ ∣_{θ = 4 5^{\circ}}$
$= \frac{u ^{2}}{g} = \frac{900}{10} = 90 m$
