Yes.
Neglecting air resistance, and using 9.8 m/s2 for the acceleration of gravity,
80 meters works out to 4.041 seconds (rounded).

How far will a freely falling object dropped from rest in eight seconds?
Assuming the object free-falls, we may use:x = x0 + v0t + at2/2x0 = 0 (we determine it)v0t = 0 (dropped from rest).a = g = 10 m/st2 = 16s2.x = 10*16 / 2 = 80m.
A spaceship has a momentum of 20000 kgms to the left and a mass of 500 kg What is the magnitude of its velocity?
80m/s
7 A stone is dropped from a 80m high bridge How long does it take to fall?
H = 1/2 G T2T2 = 2H/GT = sqrt( 2H/G ) = sqrt( 160/9.8 ) = 4.039 seconds(rounded)And if I may offer a suggestion . . . Next time you copy a question off a test or ahomework assignment, you can go ahead and drop the number '7' off the beginning.That way, it won't be so obvious, and it won't show everybody how sneaky you are.
If a hockey stick exerts a force of 40 N on a 0.5 kg puck what will the resulting acceleration be?
As long as the stick remains in contact with the puck and the force on it continues,F = m AA = F/m = (40 / 0.5) = 80 m/sec2
A musical tone sounded on a piano has a frequency of 410 Hz and a wavelength of 80m What is the speed of the sound wave?
speed of emission = wavelength per cycle * cycles per second 80 * 410 = 32,800 meters per second. (Significant figures rules may apply so 33,000 may also be a correct answer).
