Answer:
44.9 m/s
Explanation:
Initial velocity = v
Angle at which the projectile is shot at = θ = 11°
g = Acceleration due to gravity = 9.81 m/s²
Range of projectile
[tex]R=\frac {v^{2}\sin 2\theta}{g}\\\Rightarrow v=\sqrt{\frac{Rg}{sin 2\theta}}\\\Rightarrow v=\sqrt{\frac{77\times 9.81}{sin (2\times 11)}}=44.9\\\Rightarrow v=44.9\ m/s[/tex]
The take off speed of Jason Renie's motorcycle was 44.9 m/s
