Any vector can be written as components along positive X and positive Y axes.
So vector B can be written as , where is the angle between vector and positive X axis
So vector B =
So components of vector B along X -axis =-6.74 m
along Y-axis = 16.69 m
Answer:
Single replacement
Explanation:
A reaction in which one element replaces a similar element is called single replacement. In this case, C is replacing A.
Kinetic energy in the faster car is way too uzi fast to be stopped faster since it has less kodak potential energy. The slower car has more potential energy so it will be able to lil stop boat at a much smoother and shorter distance.
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
