As change is velocity is

<span>Δv=<span>10 m s<span>−1</span></span>−<span>2 m s<span>−1</span></span>=<span>8 m s<span>−1</span></span></span>

and time taken is 3 seconds so acceleration is

<span>acceleration=<span>change in velocitychange in time</span></span>

So

<span>a=<span><span>8 m s<span>−1</span></span>3 s</span>=<span>2.7 m s<span>−<span>2</span></span></span></span>

ehicle collisions involve huge amounts of energy. How does the crashworthiness of a car affect the transfer and transformations
Angelina_Jolie [31]

When the two-vehicle collides transformation of the energy is done in terms of kinetic energy.

<h3>What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

In the above problem, the Vehicle get collides so that the kinetic energy of the vehicle is converted into the kinetic energy of another vehicle the speed of the vehicle will reduce when they collide.

Momentum also gets conserved when the two vehicles collide.

Hence, the transformation of the energy is done in terms of kinetic energy.

To learn more about the law of conservation of energy, refer to brainly.com/question/2137260.

how much thermal energy is absorbed by a copper water pipe with a mass of 2.3kg when its temperature is raised from 20.0 to 80.0
Sphinxa [80]

Explanation:

q = mCΔt

q = (2.3 kg) (385 J/kg/K) (80.0°C − 20.0°C)

q ≈ 53,000 J

q ≈ 53 kJ
