Motion with constant acceleration

Two equations cover almost everything: v = v₀ + a·t tells you how fast, and d = v₀·t + ½·a·t² tells you how far.

v_{0} := 4 m/s

= 4 m / s initial velocity

a_{x} := 2 m/s^2

= 2 m / s^2 constant acceleration

t_{1} := 3 s

= 3 s elapsed time

v_{1} = v_{0} + a_{x} \cdot t_{1}

= 10 m / s velocity after t₁

d_{1} = v_{0} \cdot t_{1} + \frac{1}{2} \cdot a_{x} \cdot t_{1}^{2}

= 21 m distance covered
