Answer:
what do you mean I can't understand what do you mean this right it clearly
Newton's second law of movement numerically expresses the connection among power and changes in moving. An adjustment in speed implies, by definition, that there is an increasing speed. An outer power acts from outside the arrangement of interest, an inside power acts between components of the framework. Just outer powers influence the movement of a framework, as per Newton's first law, but the inward powers really drop, as we will find.
Answer:
Explanation:
Provided the car did not collide with anything during its slide,
Kinetic energy will convert to work of friction
½mv² = Fd
½mv² = μmgd
v = √(2μgd)
v = √(2(0.300)(9.81)(28.0))
v = 12.8377...
v = 12.8 m/s
I think the answer is B but not too sure.
Answer:
a)
b) x = 4.47 cm
c)
d) x = 1.48 cm
Explanation:
a) The center of mass is equal to:
Where m is the mass of beads and x is the distances, if x₁ = d₁, x₂ = d₂ and x₃ = d₃
b) If
m₁ = 23g
m₂ = 15 g
m₃ = 58 g
d₁ = 1.1 cm
d₂ = 1.9 cm
d₃ = 3.2 cm
c) The center of the mass of the beads realtive to the center of bead is:
d)
