Chapter 1, Problem 68MSPP
The images of trees in Figure P1.68 come from a catalog advertising fast-growing trees. If we mark the position of the top of the tree in the successive years, as shown in the graph in the figure, we obtain a motion diagram much like ones we have seen for other kinds of motion. The motion isn't steady, of course. In some months the tree grows rapidly; in other months, quite slowly. We can see, though, that the average speed of growth is fairly constant for the first few years.

A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.

A crane is lifting a batch of bricks on a pallet to an upper floor of the building. Suddenly a brick falls off the rising pallet. You measure the time it takes for the brick to hit the ground and you find it to be 2.5 seconds. The crane has height markings. You saw the brick fell off the pallet at a height of 30.7 meters above the ground. A falling brick can be dangerous, and you wonder how fast the brick was moving when it hit the ground. Since you are taking physics, you quickly calculate the answer.arrow_forwardFigure 1 shows the velocity-time graph of a person moving along one straight path called the x-axis.
