To explain: The motion of pieces of rocket after explosion in air.
Explanation of Solution
Introduction:
When rocket moves in space due to gravity it follows a parabolic path. During motion its mass is concentrated around its centre of mass.
When rocket explodes, it breaks into small pieces. After breaking, the pieces also move in parabolic path. This is because the centre of mass of pieces will not change. Hence the pieces also follow parabolic path.
Conclusion:
Rocket pieces follow the parabolic path as the pieces of centre of mass remains same.

- Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.arrow_forwardIn the given circuit the charge on the plates of 1 μF capacitor, when 100 V battery is connected to the terminals A and B, will be 2 μF A 1 µF B 3 µFarrow_forwardThe velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s.
