They travel at the same rate of speed
Answer:
It have 1.359 joule kinetic energy.
Explanation:
- Kinetic energy is defined as the energy of any object due to its state of motion.
- Mathematically kinetic energy can be calculated as:
K.E = 
...........................equation 1
where,
m= mass of object
v= velocity of that moving object
mass= 2500 lbs =
kg.
velocity= 80mph=
=
.
- Substituting the values in equation 1, we get;
K.E=
*
* 
K.E= 
Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g
ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C
Use the equation for the acceleration
A = final velocity - initial velocity divided by time final - time initial
A= 54 - 32 / 8 - 0
A= 22 / 8
A= 2.75 m/s^2
Hope this helps!
Answer:
Having a planner gives students freedom to plan, organize and keep track of their work to the best of their abilities and requirements. This has a dual benefit in that it increases the student's accountability to the commitments planned as well as provides them with a structure that contributes to their success.
