Answer:

The statement is false. See the explanation below, please.

Explanation:

The kinetic energy is that which is associated to the movement and the potential energy has been related to the position of a certain object. The sum of both, make up the mechanical energy.

A spring with spring constant 31 N/m is attached to the ceiling, and a 4.5-cm-diameter, 1.5 kg metal cylinder is attached to its

aalyn [17]

Answer:

0.315758099469 m

Explanation:

m = Mass of cylinder = 1.5 kg

$\rho$ = Density of water = 1000 kg/m³

V = Volume = Ah

A = Area = $\pi r^2$

k = Spring constant = 31 N/m

x = Displacement

g = Acceleration due to gravity = 9.81 m/s²

Here the forces are conserved

Weight of cylinder = Buoyant force + Spring force

$mg=\rho Vg+kx\\\Rightarrow mg=\rho Ahg+kx\\\Rightarrow 1.5\times 9.81=1000\times \pi(2.25\times 10^{-2})^2x\times 9.81+31x\\\Rightarrow 1.5\times 9.81=46.60213x\\\Rightarrow x=\dfrac{1.5\times 9.81}{46.60213}\\\Rightarrow x=0.315758099469\ m$

The length of the submerged cylinder is 0.315758099469 m

A runner decreases his velocity from 20 m/s to 10 m/s in 2.0 s.

Bess [88]

Acceleration = change in velocity/change in time

So you should have (20-10)/(0-2)= -10/2 = -5

So your answer is -5

inysia [295]

she could throw her tool belt in the opposite direction, sending her floating towards her ship. That would apply to Newton's Law ofwhat is in motion stays in motion unless interrupted. Therefore if you threw it one way you would keep going the other way because there are no molecules to interrupt your path.
