Answer: = . /
Explanation:
The acceleration is
= − 0
In our case, the initial velocity has minus sign.
Thus,
=
− (−0)
=
+ 0
Substituting
0 =

8.25 = 7.06 m/s
Answer: = . /
Answer:
The kinetic molecular theory of matter asserts that: Matter is made up of particles that are continually moving. All particles contain energy, however the energy fluctuates depending on the temperature the sample of matter is in. This in turn decides whether the material exists in the solid, liquid, or gaseous form.

Answer:

Explanation:
Given that the temperature of
of water and
of water are
at
and
respectively.
Let
, 
and
,
.
The specific heat capacity of water is,
.
Let the final temperature of the mixture be
.
As there is no energy loss, so, the energy loss by the water at higher temperature, i.e.
, will be equal to the energy gain by the water at lower temperature, i.e.
.

[ both sides divided by
]



Now, putting the given value in the above equation, we have


Hence, the temperature of the mixture will be
.
