A ball is thrown with an initial velocity of 8m/s in a direction that makes an angle of 35° with the horizontal. Find the horizontal range of the ball?

Respuesta :

Answer:

The horizontal range of the ball is 6.13 m

Explanation:

The initial velocity of the ball, u = 8 m/s

Angle made by the ball with the horizontal, θ = 35°

Acceleration due to gravity, g = 9.81 m/s²

The horizontal range is calculated as shown below

[tex]R=\frac{u^2\sin 2\theta}{g}[/tex]

Substitute u = 8 m/s, θ = 35°, and g = 9.81 m/s² into the range formula above

[tex]\begin{gathered} R=\frac{8^2\sin (2\times35)}{9.81} \\ R=\frac{64\sin (70)}{9.81} \\ R=\frac{64(0.9397)}{9.81} \\ R=6.13\text{ m} \end{gathered}[/tex]

Therefore, the horizontal range of the ball is 6.13 m
