Answer: 600 m
Explanation:
Speed 
is defined as the distance traveled 
in a especific time 
:
Where:
is the speed of sound
the time you hear the thunder after you see the flash of lightning
We need to find the distance at which you are from the lightning strike:
Finding :
Finally:
Given:
object = 20kg
terminal speed of object = 80 m/s
According to the problem, drag force is proportional to speed, so Fd = kv ; k is some constant
At terminal velocity Vt: Fg = Fdmg = kVtk = mg / Vt = (20.0)(9.8)/(80.0) = 2.45 kg/s
<span>Fd = kv = 2.45v</span>
Fd = 2.45 (30.0) = 73.5 N
Gravity - is the universal force that is effective over the longest distance.
Answer:
Scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis.
Explanation:
Momentum is Mass × Velocity
= 1875×22 = 41250 kg m/sec
