This can be solve by using the formula
x = (v^2) (sin 2a) / gwhere v is the intial velocitya is the angle of trajectoryg is the acceleration due to gravity (9.8 m/s2)
x = (15.5^2) (sin 2(34) / 9.8x = 22.73 m
<span>The speeds of a modern turbine that has blades that are 56 m long averages around 40 mph. It varies by how much rpm's it uses at the given time. The lower the rpm's, the lower mph it will be. Likewise, the higher the rpm's, the higher mph is will be.</span>
