Momentum P is given by:
P = mv

Given: m₁ = 62 kg, m₂ = 78.1 kg, v₁ = ?, v₂ = 0 m/s, v₁₊₂ = 1.29 m/s

before:
P = m_1 v_1 * m_2 v_2 = m_1 v_1

after:
P = (m_1 + m_2)v_{1+2}

Since momentum is conserved, the momentum before the collision must be equal to the momentum after the collision.

P = m_1 v_1 = (m_1 + m_2)v_{1+2} \\ v_1 =  \frac{(m_1 + m_2)v_{1+2}}{m_1}

Solve for v₁.

Real images can be upright or inverted.
Nadusha1986 [10]
Real images can be either upright or inverted. Real images can be magnified in size, reduced in size or the same size as the object. Real images can be formed by concave, convex and plane mirrors. Real images are not virtual; thus you could never see them when sighting in a mirror.

A teacher discusses a scientific theory that has been in place for almost a century. which would present the greatest challenge
Umnica [9.8K]

Answer: The theory might have become Obsolete or Superseded

Explanation:

A theory becomes obsolete or superseded if it becomes inadequate, false or incomplete in how its describes reality. It does not matter if it was once accepted. There are some theories such as Lysenkoism that are currently described as being obsolete because it does not conform to current reality. Another example of a theory that was superseded is the phlogiston theory. It was replaced a different theory of energy.
