Question

A batsman hits a ball from the ground level with speed of 28 ms -1 in a direction 30° above the horizontal. How far from the batsman does the ball land for the first time? (A) 45 m (B) 53 m (C) 59 m (D) 69 m

R=(u2 ⋅ sin 2 θ/g)=((28)2 ⋅ sin 2(30°)/9.8)=69 m

Q. A batsman hits a ball from the ground level with speed of $28 m s^{- 1}$ in a direction $3 0^{\circ}$ above the horizontal. How far from the batsman does the ball land for the first time?

$45 m$

$53 m$

$59 m$

$69 m$

$R = \frac{u ^{2} \cdot s i n 2 θ}{g} = \frac{( 28 ) ^{2} \cdot s i n 2 ( 3 0 ^{\circ} )}{9.8} = 69 m$
