Solutions Mathalino Upd - Rectilinear Motion Problems And
16.1 t squared plus open paren 40 t minus 16.1 t squared close paren equals 80 ⟹ 40 t equals 80 ⟹ t equals 2 seconds 2. Calculate the meeting point location back into the first equation: ft from the top
Let:
Stone 2 is thrown 1 second later, so its travel time = t - 1 = 2.193 s. Initial velocity u (downward positive): y = u·t₂ + ½ g t₂² → 50 = u(2.193) + ½ (9.81)(2.193)² ½(9.81)(4.809) = 23.58 Thus 50 = 2.193u + 23.58 → 2.193u = 26.42 → u ≈ 12.04 m/s downward. rectilinear motion problems and solutions mathalino upd
