Two blocks can collide in a one-dimensional collision. The block on the left hass a mass of 0.40 kg and is initially moving to t
Dmitrij [34]

Answer:

The velocity of the first block is 1.15m/s while of the second block 2.56m/s.

Explanation:

Momentum is only conserved in an isolated system, and because this problem requires us to find the value of the two variables, we need two equations; therefore, to conserved momentum the energy must be released in to the system only after the collision has occurred.

Therefore, from conservation of momentum

m_1v_1= m_1v_{1f}+m_2v_{2f}

0.4(2.4)= 0.4v_{1f}+0.5v_{2f}

\boxed{\:0.96= 0.4v_{1f}+0.5v_{2f}}

and from conservation of energy

$\frac{1}{2}m_1v_1^2+1.2 = \frac{1}{2} m_1v_{1f}^2+\frac{1}{2}m_2v_{2f}^2  $

m_1v_1^2+2.4 =  m_1v_{1f}^2+m_2v_{2f}^2}

$\boxed{\:3.804=  0.4v_{1f}^2+0.5v_{2f}^2.}$

Thus, we have two equations and two unknowns

(1). \: 0.4v_{1f}+0.5v_{2f}=0.96

{(2). \:  0.4v_{1f}^2+0.5v_{2f}^2 =3.804

which has solutions

(v_{1f}, v_{2f}) = (1.15,2.56)

and

(v_{1f}, v_{2f}) = (1.15,-2.56)

Since the blocks cannot pass through each other, the 0.5kg block cannot have v_{2f} = -2.56m/s  (moves to the left) while the 0.4 kg block has v_{1f} = 1.15m/s (moves to the right); therefore, we take the first solution for the velocities:

(v_{1f}, v_{2f}) = (1.15,2.56).

Thus , the velocity of the first block is 1.15m/s while of the second block 2.56m/s.

What is the force applied to a baseball that has a mass of 142kg and has a acceleration of 30m/s to the power of 2
aev [14]
  • Mass=m=142kg
  • Acceleration=a=30m/s
  • Force=F

Using Newton's second law

\\ \sf\Rrightarrow F=ma

\\ \sf\Rrightarrow F=142(30)

\\ \sf\Rrightarrow F=4260N

two children having a disagreement pull on a 50N sled in opposite directions. one pulls with a force of 300N east, the other wit
prohojiy [21]
<span>Since forces are vector quantities, we must indicate direction using positive and negative values. East will be assigned positive and west will be negative. Friction will act as a negative force since it impedes action. To calculate the net force we sum the vector quantities, as follows. Net force equals 50n which is derived by the following calculation: 300n-220n-30n.</span>
