Answer:
90.44 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 30 m/s
Angle of projection (θ) = 40°
Acceleration due to gravity (g) = 9.8 m/s²
Range (R) =?
The range of the ball can be obtained as follow:
R = u² Sine 2θ / g
R = 30² Sine (2×40) / 9.8
R = 900 Sine 80 / 9.8
R = 900 × 0.9848 / 9.8
R = 886.32 / 9.8
R = 90.44 m
Therefore, the range of the tennis ball is 90.44 m
