PLEASE HELP!! A 2.0 kg moving cart hits a spring with a spring constant 50.0 N/m. Assume the system is frictionless. When the ca

rt has come to rest, how far has the spring compressed?

Explanation:

A spring has a spring constant, (k), of 3 N/m. It is stretched until it is extended by 50 cm. Calculate the elastic potential energy stored by the spring, assuming it is not stretched beyond the limit of proportionality.

First convert centimetres to metres:

50 cm = 50 ÷ 100 = 0.5 m

Then calculate using the values in the question:

Ee=12 k e2

Ee=12×3×0.52

Ee=1.5×0.25

Ee=0.375 J

gas stored in a tank at 273 k has a pressure of 50kpa. what happens to the volume when the pressure is decrease due to the added
AfilCa [17]

I can't think of any way that pressure can be decreased due to added pressure.

Be that as it may, and it certainly still is ...

No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change.  Any sample
of gas always expands to fill the container in which it's confined. 
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

A ball is shot from the ground straight up into the air with initial velocity of 42 ft/sec. Assuming that the air resistance can
Volgvan

Answer:

Maximum height of the ball, h(t) = 27.56 m

Explanation:

It is given that, a ball is shot from the ground straight up into the air with initial velocity of 42 ft/sec.      

The height of the ball as a function of time t is given by :

h(t)=h_o+v_ot-16t^2

h₀ is initial height, h₀ = 0

So, h(t)=42t-16t^2 .........(1)

For maximum/minimum height,  \dfrac{dh(t)}{dt}=0

42-32t=0...(2)

t = 1.31 s

Differentiating equation (2) wrt t

h''(t) = -32 < 0

So, at t = 1.31 seconds we will get the maximum height.

Put the value of t in equation (1)

h(t)=42\times 1.31-16\times (1.31)^2

h(t) = 27.56 m

Hence, this is the required solution.

A parallel-plate capacitor is charged by a 14.0 V battery, then the battery is removed. You may want to review (Pages 692 - 695)
Anika [276]

Answer:

Potential Difference = 14 V

Explanation:

We are told that when the capacitor plates are charged to a certain voltage, then we have;

ΔV = 14 volts

Now, the battery is disconnected, so here we have the potential difference between the plates to be given by the formula;

ΔV = Q/C

Now, the charge is conserved on the plates and the capacitance is constant, therefore in this case, the potential difference will remain the same.

Thus;

Potential Difference = 14 V
