- A fireworks rocket is launched vertically into the night sky with an initial speed of 41.6 m/s . The rocket coasts after being launched, then explodes and breaks into two pieces of equal mass 2.20 s later. If each piece follows a trajectory that is initially at 43.0 degrees to the vertical, what was their speed immediately after the explosion? What is the velocity of the rocket's center of mass before the explosion? What is the velocity of the rocket's center of mass after the explosion? What is the acceleration of the rocket's center of mass before the explosion? What is the acceleration of the rocket's center of mass after the explosion?A 0.455-kg hockey puck, moving east with a speed of 5.05 m/s, has a head-on collision with a 0.730-kg puck initially at rest.

It bounces off with the same speed at an angle shown in figure. Assume that the collision lasts for 10.4ms. To determine the following (i) impulse ‘J’ experienced by the ball?(ii) average force ‘F’ exerted by the ball on the wall? Hint:Steps to find the Impulse and net force exerted by the ball:❖ Resolve the components and find ??? , ???❖ The ball has the same speed before and after bouncing from the wall, the momentum in the x direction remains the same and hence Pxi = Pxf. therefore ∆?? becomes zero ❖ The initial and final momentum in the y direction is changed and hence ∆?? = ?(??? − ???). Substitute ??? , ??? in the formula to determine ∆??❖ Calculate the impulse using the formula J = ∆? = ∆?? − ∆??❖ Find the force exerted by the ball through the formula F = ∆?/∆?
