5 0

<u>Answer:</u>

235 m/s

<u>Explanation:</u>

v = u + at

where v = final speed,

u = initial speed (10 m/s),

a = acceleration (15 m/s²),

t = time taken (15 s).

Substituting into the formula:

v = 10 + (15 x 15)

v = 10 + 225

v = 235 m/s

Rocks that are formed as a result of deposits from weathering and erosion

zimovet [89]

<h2>Answer: Sedimentary rocks </h2>

Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks.

These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).

A hockey puck sliding along frictionless ice with speed v to the right collides with a horizontal spring and compresses it by 1.

patriot [66]

Answer:

The spring's maximum compression will be 2.0 cm

Explanation:

There are two energies in this problem, kinetic energy $K= \frac{mv^{2}}{2}$ and elastic potential energy $U= \frac{kx^{2}}{2}$ (with m the mass, v the velocity, x the compression and k the spring constant. ) so the total mechanical energy at every moment is the sum of the two energies:

$E=K+U$

Here we have a situation where the total mechanical energy of the system is conserved because there are no dissipative forces (there's no friction), so:

$E_{i}=E_{f}$

$K_{i}+U_{i}=K_{f}+U_{f}$

Note that at the initial moment where the hockey puck has not compressed the spring all the energy of the system is kinetic energy, but for a momentary stop all the energy of the system is potential elastic energy, so we have:

$K_{i} = U_{f}$

$\frac{mv^{2}}{2}=\frac{kx^{2}}{2}$ (1)

Due conservation of energy the equality (1) has to be maintained, so if we let k and m constant x has to increase the same as v to maintain the equality. Therefore, if we increase velocity to 2v we have to increase compression to 2x to conserve the equality. This is 2(1.0) = 2.0 cm
