Asoccer ball is traveling at a velocity of 50 m/s. the kinetic energy of the ball is 500 j. what is the mass of the soccer ball? (formula: ) 0.1 kg 0.2 kg 0.4 kg 0.5 kg

Hey there Fam

the only thing dat brought me here is Soccer ball XD

anyways hahahaha the answer is

C)0.4

thank you

YT

Answer : The mass of the soccer ball is, 0.4 Kg

Explanation : Given,

Kinetic energy  of the ball = 500 J

Velocity of the ball = 50 m/s

Formula used :

where,

K.E = kinetic energy  of the ball

m = mass of the soccer ball

v = velocity of the ball

Now put all the given values in this formula, we get  mass of the soccer ball.

Therefore, the mass of the soccer ball is, 0.4 Kg

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
