1. A bullet with mass 30 g travels horizontally at a speed of 500 m/s. It strikes a block of Jell-O of mass 30.0 kg that is initially at rest on a friction- less table (In case you are wondering how that is possible, the Jell-O is stuck to a very light mat that slides easily on the table.) The bullet embeds 25 cm into the block of Jell-O. (a) Find the magnitude and direction of the velocity of the bullet/Jell-O combination immediately after the impact is finished. (b) Find the magnitude and direction of the impulse from the bullet on the block. (c) If it took 3 ms for the bullet to change speed from 500 m/s to the final speed after impact, what is the average force between the block and the bullet during this time?
