A Horizotal force of 0.80N is required to pull a 5kg block
across a table top at a constant speed with the block initially
at rest, a 20g bullet fired horizontally into the block causes
the block to slide 1.5m before coming to rest again Determine the
Speed v of the bullet, where the bullet is assumed to be
embedded in the block

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
