In an inelastic collision, as compared to an elastic collision, what is to be expected?.

1 answer:

3 0

The loss or conservation of kinetic energy is the difference between an elastic and an inelastic collision. Kinetic energy is not preserved in an inelastic collision, and it will change forms into sound, heat, radiation, or another form. The kinetic energy in an elastic collision is preserved and does not change forms.

8. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bott

nasty-shy [4]

Answer: The ball is travelling with a speed of 5.5 m/s after hitting the bottle.

Explanation:

To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

where,

$m_1,u_1\text{ and }v_1$ are the mass, initial velocity and final velocity of ball.

$m_2,u_2\text{ and }v_2$ are the mass, initial velocity and final velocity of bottle.

We are given:

$m_1=0.4kg\\u_1=18m/s\\v_1=?m/s\\m_2=0.2kg\\u_2=0m/s\\v_2=25m/s$

Putting values in above equation, we get:

$(0.4\times 18)+(0.2\times 0)=(0.4\times v_1)+(0.2\times 25)\\\\v_1=5.5m/s$

Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.

8. A 60 kg runner has 1500 J of kinetic energy. How fast is he moving?

tresset_1 [31]

Answer: 7.07 m/s

Explanation:

Mass of runner = 60 kg runner

Kinetic energy = 1500J

Speed of runner = ?

Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass and speed by which it moves.

Hence, K.E = 1/2 x mass x (speed)^2

1500J = 1/2 x 60kg x (speed)^2

1500J = 30kg x (speed)^2

(speed)^2 = 1500J/30kg

(speed)^2 = 50

To get the value of speed, find the square root of 50

speed = √50

speed = 7.07 m/s

Thus, the runner moves as fast as 7.07 m/s

Factors that affect the light intensity received from a source

Roman55 [17]

Light intensity and distance is interrelated. When the distance changes, the intensity of light changes. This relationship is called inverse-square relationship. The inverse-square relationship refers to the fact that when distance changes, light intensity also changes: inverse because when distance decreases, light density increases and when distance increases, the latter decreases; square refers to the fact that light intensity and distance is not a one-to-one relationship.
