WebA fireworks rocket is fired vertically upward. At its maximum height of 80.0 m, it explodes and breaks into two pieces, one with mass 1.40 kg and the other with mass 0.28 kg. In the explosion, 860 J of chemical energy is converted to kinetic energy of the two fragments. (a) What is the speed of each fragment just after. Webproblem. 8.97. We have a fireworks rocket that it's launched vertically. At its maximum height of 80 meters, it explodes into two pieces with the mass is shown… cirrus safety

WebA firework rocket is fired vertically upwards. The fuel burns and produces a constant upwards force on the rocket. After 5 seconds there is no fuel left. Air resistance is negligible. ... Verb Articles Some Applications of Trigonometry Real Numbers Pair of Linear Equations in Two Variables. WebThe projectile question assumes the movement along the x-axis stops when the object touches the ground again (or question will specify what is the displacement upon first hitting the ground) co30*10 will give us the "speed" along x-axis the ball will move not the total displacement. In this case 8.66m/s. WebSince the firework rocket is launched vertically upward, we need to calculate the maximum height (relative to the ground) the rocket achieves. yf = y0 +v0y ∆t − 1 2 g∆t2 (10) (or Work-Energy) −mgyf = − 1 2 mv2 0 (11) yf = v2 0 2g = 81.55m (Max. height before explosion.)
