Assuming the raindrop was stationary relative to the vertical distance to the ground at the start:
D=0.5at where d is distance, a is acceleration and t is time
D is 300 meters
a is 9.8 meter/sec squared
Solve for t in seconds
t = 61.2 seconds
v=at where v is velocity
a is 9.8 meters per second squared
t is 61.2 seconds
solve for v
v = 600 meters per second.
If it had an initial vertical velocity (v0) at the start :
d= 0.5at+v0t
and
v=at+v0
Hello there.

Answer:They stop because jet streams follow boundaries between hot and cold air.

Answer:
Explanation:
We shall apply law of conservation of momentum to know the Speed of northward moving vehicle before collision to check the veracity of driver's statement .
Let v be the velocity of composite mass after collision
Applying law of conservation of momentum in north direction
m v₂ = 2m v sin55.08
Applying law of conservation of momentum in east direction
m x 13 = 2m v cos55.08
Dividing these two equations
v₂ / 13 = tan55.08
v₂ = 13 tan55.08
= 18.62 m/s
= (18.62 x60 x 60) / 1000
= 67 km/h
= 67 x 5/8 mi/h
= 42 mi/h
So he is lieing.
For starters, this question isn’t really about relativity. It’s about
energy, and E=mc^2 only makes sense if energy has the units of
(mass)*(velocity)^2. So we might as well ask: why is kinetic energy
defined as KE = ½*mv^2?
