Two Balls Thrown Upward at Different Times: Finding When They Meet
Physics · Physics — Grade 11Ball A is thrown vertically upward with an initial velocity $v_0$. Ball B is thrown upward from the same point with the same initial velocity $v_0$, but $t$ seconds later. Given that $t < \dfrac{2v_0}{g}$, determine the …

Rectilinear Motion with Constant Acceleration: Three-Phase Train Problem
Physics · Physics — Grade 11A train starts from rest at station A and accelerates at $0.5 \text{ m/s}^2$ for $60 \text{ s}$. Afterwards it travels with a constant velocity for $15 \text{ min}$. It then decelerates at $1 \text{ m/s}^2$ until it is b…
