Answer: 39.08664m
Normal free fall:
2s = 19.6133m/s
1s = 9.08665m/s
Assuming there's no air resistance:
The first second of the fall it will travel 15m
since the initial speed of the ball is 15m/s
this leaves us with 1 second, however by the time the ball ha traveled 1 second it will be accelerated by the force of gravity (9.08665)
15 + 9.08665 = 24.08665
We're already travelled 15m
and now 24.08665 will be covered in
the last second.
24.08665 + 15 = 39.08664m
-/
if we're gonna be technical:
a coins terminal velocity is only roughly around 19km/s so it wouldn't even travel much
(a brainliest would be appreciated)
Answer:
By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star.
Explanation:
have a great day ahead ♥️
The velocity of the girl is -4.8 m/s.
Using the principle of conservation of linear momentum, The total momentum of bodies before and after collision is constant. Since the two objects are stationary, the initial momentum of each body is zero.
Thus;
0 = (80 × 3) + (50 × v)
0 = 240 + 50 v
-240 = 50 v
v = -240/50
v = -4.8 m/s
Note that the negative sign shows that the velocity of the girl is in opposite direction that that of the girl.
