A 14.0-lb beam is supported by two 8.00-lb cylinders placed under it. A 5.00-lb magnitude force pulls the beam at its end, coplanar with its surface as depicted. As the beam moves forward, the cylinders roll without slipping relative to the floor and beam. (a) At the instant the cylinders are equidistant from each end, what is the acceleration of the beam? (b) What is the acceleration of the cylinders? (c) Determine the frictional forces at this time

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

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)
