When chasing a hare along a flat stretch of land, a greyhound leaps into the air at a speed of 9.9 m/s, at an angle 27 degrees above the horizontal
Vf= Viy + at
displacement= Vyt + .5at squared
0= 4.95 (y component for velocity) + 9.81t
t= .504
y= 4.95x.504 + .5x9.81x.504 squared
y displacement= 3.78
using tan 27= 3.745/x
x displacement= 7.33
multiplied by 2 = 14.66
