Always cross-verify the dimensional consistency of your final derived formula. If your LHS dimensions do not match the RHS, you know there is a calculation error. vmax=rg(μ+tanθ1−μtanθ)space v sub m a x end-sub equals

The minimum speed needed for an object to break free from Earth's gravitational pull.Work required to move mass from surface to infinity ( ∞infinity We know that angular momentum is:

v2=(2m1m1+m2)u1+(m2−m1m1+m2)u2space v sub 2 equals open paren the fraction with numerator 2 m sub 1 and denominator m sub 1 plus m sub 2 end-fraction close paren u sub 1 plus open paren the fraction with numerator m sub 2 minus m sub 1 and denominator m sub 1 plus m sub 2 end-fraction close paren u sub 2 Unit 4: Rotational Motion Torque and Angular Momentum Relation τ⃗modified tau with right arrow above ) is the rotational analog of force, and angular momentum ( L⃗modified cap L with right arrow above ) is the rotational analog of linear momentum. We know that angular momentum is:
