Respuesta :
The arrow is fired with an initial upward velocity of 32 ft/s.option 4 is correct.
What is velocity?
The change of displacement with respect to time is defined as the velocity. Velocity is a vector quantity. it is a time-based component.
Velocity at any angle is resolved to get its component of x and y-direction.
The given data in the problem is;
g is the acceleration due to gravity
vâ‚€ is the initial speed=?
h is the initial height = 4+32t-16t²
The relation of the height with the velocity and time is given according to the motion will be;
[tex]h(t)= -\frac{1}{2}gt^ 2+v_0t+h_0 \\\\[/tex]
h  = 4+32t-16t²
Hence the value of the vâ‚€ will be 32 ft/sec.
