Manipulating Variables

Solve F = ma for a

(a)  

• a= m/F
• a=F/m
• a= F- m
• a= F + m

Solve x = vt for v

(a)  

• v = x- t
• v= t/x
• v = x/t
• v = x+t

Solve power = work / time for work

• work = power * time (* means multiply)

• work = power / time

• work = time / power

• work = power - time

Solve power = work / time for time

• time = power * work (* means multiply)

• time = power / work

• time = work / power

• time = power + work

solve x = 1/2 a t² for a

(a)  

• a = 1/2 x t²
• a = 1/2 x / t²
• a= square root (2x / t)
• a = 2x / t²

Solve for t.

(t / 6) = 4

(a)  

• t = 1.5
• t = 24
• t = 2
• t = 0.67

Solve for v. E = 1/2 mv²

• v = 1/2 E/m^0.5

• v = (E/2m)²

• v = square root(2m/E)

• v = ( 2E/m)^0.5

Solve for m_2i in the following equation, m_1i*v_1i + m_2i*v_2i = m_1f*v_1f + m_2f*v_2f

• (m_1f*v_1f + m_2f*v_2f - m_1i*v_1i)/v_2i

• (m_1f*v_1f + m_2f*v_2f/v_2i) - m_1i*v_1i

• (m_1i*v_1i - m_1f*v_1f + m_2f*v_2f)/v_2i

• (m_1f*v_1f + m_2f*v_2f )/ (m_1i*v_1i + v_2i
