Consider the collision of two identical particles, with m1 = m2 = 10 g. The initial velocity of particle 1 is v1 and particle 2 is initially at rest, v2 = 0 m/s.. 1 2 v1 After an elastic head-on collision, the final velocity of particle 2 is v′ 2 and given by.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
