In an out of control ceramics workshop, two clay balls collide in mid air and stick together. the first has mass 3.1 kg and coll

ides with a second that is initially at rest. the composite system moves with a speed equal to one-third the original speed of the 3.1 kg ball. what is the mass of the second sphere?

<span>We know that the first ball has a mass of 3.1 kg and moves at speed called V1 The second ball has a mass of M2 unknown and the both together moves a speed equal to V = V1/3

   The momentum keeps constant before and after balls collide, so:
 M1*V1 + M2*V2 = M*V
 3.1*V1 + M2*0 = (3.1+M2)*V1/3
 3.1*V1 = 3.1/3*V1+M2*V1/3
 3.1*V1-3.1/3*V1 = M2*V1/3
 (3.1-3.1/3)*V1 = M2*V1/3
 2*3.1/3 = M2/3
 M2 = 6.2
   Then the mass of the second ball is 6.2 kg</span>

What is the formula for volume using density and mass
lawyer [7]

The definition of density is

                                                       Density                  = (mass) / (volume)

Multiply each side by 'volume' :    (density) x (volume) = (mass)

Divide each side by 'density' :                         Volume = (mass) / (density)

Calculate the kinetic energy of a 0.032 kg ball as it leaves a hand to be thrown upwards at 6.2 m/s
AnnZ [28]

Answer:

The ball will have a kinetic energy of 0.615 Joules.

Explanation:

Use the kinetic energy formula

E_k = \frac{1}{2}mv^2 = \frac{1}{2}0.032kg\cdot 6.2^2 \frac{m^2}{s^2}= 0.615J

The kinetic energy at the moment of leaving the hand will be 0.615 Joules. (From there on, as it ball is traveling upwards, this energy will be gradually traded off with potential energy until the ball's velocity becomes zero at the apex of the flight)
