Now, find the distance (s): s = 0 m/s × 10 s + (1/2) × 1.5 m/s² × (10 s)² = 75 meters rectilinear motion problems and solutions mathalino upd

Acceleration is constant.

Problem solving at MATHalino generally falls into three categories based on acceleration: Governing Equations Context/Usage Uniform Motion Constant velocity; zero acceleration. Constant Acceleration Used for cars braking or free-falling bodies ( Variable Acceleration Requires calculus (differentiation or integration).

Compute positions: [ s(0) = 2,\ s(1) = 1 - 6 + 9 + 2 = 6,\ s(3) = 27 - 54 + 27 + 2 = 2,\ s(5) = 125 - 150 + 45 + 2 = 22 ] Displacement = ( s(5) - s(0) = 22 - 2 = 20 ) m (positive, to the right). $$v = t^2 - 4t$$ At $t=3$: $v

Integrate acceleration. $$v = \int a , dt = \int (2t - 4) , dt = t^2 - 4t + C_1$$ At $t=0, v=0 \implies C_1 = 0$. $$v = t^2 - 4t$$ At $t=3$: $v = 3^2 - 4(3) = 9 - 12 = -3 , \textm/s$.

[ v = gt, \qquad h = \tfrac12 gt^2, \qquad v^2 = 2gh ]
