Answer:

4.00m

Step-by-step explanation:

at that instant where it is dropped all the mechanical energy is gpe which is 71.9

and the formula for gpe = mass (1.80) * height * gravitational field strength (i'm using 10 m/s2)

height of football stadium

= 71.9/[(1.80)(10)]

= 71.9/18.0

= 3.99444..

= 4.00 (3 sf)
