A fireworks rocket is fired vertically up. at its maximum height of 60.0m, it explodes and breaks into two pieces, one with mass 1.20kg and the other with mass 0.30kg, both with horizontal initial velocities. in the explosion, 0.960kJ of chemical energy is converted to the kinetic energy of the two fragments.
What is the speed of each fragment just after the explosion? it is observed that the two fragments hit the ground at the same time. what is the distance between the points on the ground where they land? Assume that the ground is level and air resistance can be ignored.
Explain the difference in the distances travelled by the fragments if any.
i found out that the battery in a branch is 20 v and in the other is 5 V .. The R in 20v branch is 5 and in the other is also 5 .. So how is the voltage constant ?!! Knowing that in parallel circuits V is constant ..could you clarify this to me please ??
