kotegsom [21]

Answer:

The take-off speed is 41.48 \frac{m}{s}

Explanation:

Given :

Range R = 77 m

Projectile angle \alpha  = 13°

From the formula of range,

  R = \frac{v_{o} ^{2}   }{g} \sin 2\alpha

Find the velocity from above equation,

  v_{o} = \sqrt{\frac{gR}{\sin 2 \alpha } }

  v_{o} = \sqrt{\frac{9.8 \times 77}{\sin 26} }                              ( ∵ g = 9.8 \frac{m}{s^{2} } )

  v_{o} = 41.48 \frac{m}{s}

Therefore, the take-off speed is 41.48 \frac{m}{s}
