shown in the figure both parts of a composite object are inititally moving to the RIGHT at a speed of 1.8m/s. Suddenly an explosive at the border of the two parts detonates. After the explosion the 5.0 kg part moves to the Left at 0.6m/s. (a) Find the velocity ((4.5 pts) magnitude and (0.5 pt) direction - specify LEFT or RIGHT) of the 2.5 kg part after the explosion. Before explosion 1.8 m/s 5.0kg 2.5kg 0.6 m/s After explosion 5.0kg 2.5kg v=? (b) Find the impulse ((2.5 pts) magnitude and (0.5 pt) direction - specify LEFT or RIGHT) on the 5.0 kg part during the explosion.
