mixer [17]

Answer:

1.2 seconds

Explanation:

distance = ((final speed + initial speed) * time)/2

Here given:

  • distance: 3.8 meter
  • initial speed: 6.4 m/s
  • final speed: 0 m/s

Solving steps:

3.8 = ((0 + 6.4) * time))/2

3.8 = 3.2(time)

time = 3.8/3.2

time = 1.1875 seconds ≈ 1.2 seconds

dolphi86 [110]

Answer:

Explanation:

To convert gram / centimeter³ to kg / m³

gram / centimeter³

= 10⁻³ kg / centimeter³

= 10⁻³  / (10⁻²)³ kg / m³

= 10⁻³ / 10⁻⁶ kg / m³

= 10⁻³⁺⁶ kg / m³

= 10³ kg / m³

So we shall have to multiply be 10³ with amount in gm / cm³ to convert it into kg/m³

2.33 gram / cm³

= 2.33 x 10³ kg / m³ .

Two 0.40 kg soccer ball collide elastically in a head-on collision. The first ball starts at rest, and the second ball has a spe
yulyashka [42]

Explanation:

Mass of two soccer balls, m_1=m_2=0.4\ kg

Initial speed of first ball, u_1=0

Initial speed of second ball, u_2=3.5\ m/s

After the collision,

Final speed of the second ball, v_2=0

(a) The momentum remains conserved. Using the conservation of momentum to find it as :

m_1u_1+m_2u_2=m_1v_1+m_2v_2

v_1 is the final speed of the first ball

0.4\times 0+0.4\times 3.5=0.4v_1+0.4\times 0

0.4\times 3.5=0.4v_1

v_1=3.5\ m/s

(b) Let E_1 is the kinetic energy of the first ball before the collision. It is given by :

E_1=\dfrac{1}{2}mu_1^2

E_1=\dfrac{1}{2}\times 0.4\times 0

It is at rest, so, the kinetic energy of the first ball before the collision is 0.

(c) After the collision, the second ball comes to rest. So, the kinetic energy of the second ball after the collision is 0.

Hence, this is the required solution.
