A motorist driving at 25 meters/second decelerates to

timama [110]

Kinetic energy = (1/2) (mass) (speed)²

Before slowing down, the car's speed is 25 m/s,
and its kinetic energy is ...

   (1/2) (1,500 kg) (25 m/s)²

      = (1/2) (1,500 kg) (625 m²/s²)

      =    468,750 joules .

After slowing down, the car's speed is 15 m/s,
and its kinetic energy is ...

   (1/2) (1,500 kg) (15 m/s)²

      = (1/2) (1,500 kg) (225 m²/s²)

      = 168,750 joules.

The car lost (468,750 - 168,750) = 300,000 joules of K.E.

The law of Conservation of Energy says:

That 300,000 joules had to go somewhere.

If it's a standard, gas-powered car, then the kinetic energy got
put into the brakes. The energy turned into heat, and the heat
was carried off in the air.

If it's a more modern electric or hybrid car, then the kinetic energy
spun the wheel motors, turning them temporarily into electrical
generators. The generators converted the kinetic energy into
electrical energy, which got put back into the car's batteries, and
could be used again. That's why electric cars use less gas.

$\large{\underline{\underline{\maltese{\pink{\pmb{\sf{ \; Question \; :- }}}}}}}$

An automobile with a mass of 1250 kg accelerates at a rate of 4 m/sec² in the forward direction. What is the net force acting on the automobile?

_________________________________________

$\large{\underline{\underline{\maltese{\green{\pmb{\sf{ \; Given\; :- }}}}}}}$

➢ Mass of the automobile = 1250 kg
➢ Acceleration of the body = 4m/sec²

_________________________________________

$\large{\underline{\underline{\maltese{\orange{\pmb{\sf{ \; To \: Find \; :- }}}}}}}$

Net force acting on the automobile = ?

_________________________________________

$\large{\underline{\underline{ \bigstar{{\pmb{\sf{ \; Concept \: and \: Formula \: Used \; :- }}}}}}}$

➯ Force is defined as the product of the mass of the body and its acceleration.

$\bigstar \: \small{ \fbox {\textsf {\textbf{F = ma}}}}$

Where :

F = Force
m = Mass of the body
a = acceleration due to gravity

$\large{\underline{\underline{ \bigstar{{\pmb{\sf{ \; Substituting \: the\: Given\: Values :- }}}}}}}$

$⇝ \: \: \small \textsf {\textbf{ F = (1250 × 4) N }}$

$⇝ \: \: \small \textsf {\textbf{ F = 5000 N }}$

$\large{\underline{\underline{ \bigstar{{\pmb{\sf{ \; Therefore \; :- }}}}}}}$

❝ The net force acting on the automobile is 5000 N. ❞

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?

Alex787 [66]

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
