Answer:
16.63265306 Kg
Explanation:
This is a Newtons to weight conversion.
Fg = weight
Fg = N/9.8
You're saying that it is the same thing to add or subtract B. This means that B must be the zero vector.
This works with numbers as well, if you feel more familiar to think it this way: in general, if you add something to a number you make it bigger, whereas if you subtract it, you make it smaller.
The only way to cause adding and subtracting to be the same thing is to add or subtract zero: in both cases, you're doing nothing.
Explanation:
Given:
Δy = d
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2(g)(d)
v = √(2gd)
If we double d:
√(2g (2d))
√(4gd)
Compared to the first velocity:
√(4gd) / √(2gd)
√2
So the new velocity is √2 greater than the first velocity.
√2 v
10
Explanation: V=AxR
2x5 (2 times five)
before the firecracker explodes it has potential energy which is transformed into kinetic energy when it explodes.
