A 10 g bullet is fired into, and embeds itself in, a 2 kg block attached to a spring with a force constant of 19.6 n/m and whose

dmitriy555 [2]

Answer:

$x=0.478\ m$ is the compression in the spring

Explanation:

Given:

mass of the bullet, $m=10\ g=0.01\ kg$

mass of block, $M=2\ kg$

stiffness constant of the spring, $k=19.6\ N.m^{-1}$

initial velocity of the spring just before it hits the block, $u=300\ m.s^{-1}$

Now since the bullet-mass gets embed into the block, we apply the conservation of momentum as:

$m.u=(M+m).v$

$0.01\times 300=(2+0.01)\times v$

$v=1.4925\ m.s^{-1}$

Now this kinetic energy of the combined mass gets converted into potential energy of the spring.

$\rm Kinetic\ energy=Spring\ potential\ energy$

$\frac{1}{2} (M+m).v^2=\frac{1}{2} k.x^2$

$\frac{1}{2} \times (2+0.01)\times 1.4925^2=\frac{1}{2} \times 19.6\times x^2$

$x=0.478\ m$ is the compression in the spring

How does water affect the coastal climate?

JulijaS [17]

Large bodies of water such as oceans, seas, and large lakes affect the climate of an area. Water heats and cools more slowly than land. Thus, in the summer, the coastal regions will stay cooler and in winter warmer. A more moderate climate with a smaller temperature range is created.

Answer: The correct answer is-

C) The cost to develop the technology would be greater than what could be made in profits.

As per the information in the question, company believes that electric cars are the future of the automotive industry.

It indicates that in future, automobile industries will flourish and get maximum profit through selling of electric cars. This idea will only be fulfilled if the cost to develop the technology would be less and the profit made out of it is significantly larger.

Thus, out of the given factors, only option C) The cost to develop the technology would be greater than what could be made in profits will prohibit the company from developing the idea.
