An arrow is shot straight upward with an initial velocity of 90 m/s. How high would the arrow rise? (Assume the acceleration is -9.81 m/s/s)

not moving. pos accel,

a is the best answer your welcome

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
