Consider a collision in one dimension that involves two objects of masses 4.5 kg and 6.2kg. The larger mass is initially at rest, and the smaller mass has an initial velocity of 16 m/s[E]. The final velocity of the larger object is 10.0 m/s [E]. Calculate the final velocity of thesmaller object after the collision.

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?
