Textbook Question

Chapter 4, Problem 46PCE

Predict/Explain You throw a ball into the air with an initial speed of 10 m/s at an angle of 60° above the horizontal. The ball returns to the level from which it was thrown in the time T. (a) Referring to Figure 4-28, which of the plots (A, B or C) best represents the speed of the ball as a function of time? (b) Choose the best explanation from among the following:

I. Gravity causes the ball’s speed to increase during its fight.
II. The ball has zero speed at its highest point.
III. The ball’s speed decreases during its flight, but it doesn’t go to zero.

Students have asked these similar questions

A bomber is flying at 130 m/s horizontally at an altitude of 350 m above the ground. When the planeis directly above a building, a bomb is released from the plane. How far from the building will the bomb land when it hits the ground? Ignore air resistance. Kindly provide a force body diagram and complete solution. Topic is constant acceleration-2D-motion

The shot put is a track-and-field event in which athletes throw a heavy ball - the shot - as far as possible. The best athletes can throw the shot as far as 23 m . Athletes who use the "glide" technique push the shot outward in a reasonably straight line, accelerating it over a distance of about 2.0 m . What acceleration do they provide to the shot as they push on it? Assume that the shot is launched at an angle of 37 degrees, a reasonable value for an excellent throw. You can assume that the shot lands at the same height from which it is thrown; this simplifies the calculation considerably, and makes only a small difference in the final result.

In the winter sport of curling, players give a 20 kg stone a push across a sheet of ice. The stone moves approximately 40 m before coming to rest. The final position of the stone, in principle, only depends on the initial speed at which it is launched and the force of friction between the ice and the stone, but team members can use brooms to sweep the ice in front of the stone to adjust its speed and trajectory a bit; they must do this without touching the stone. Judicious sweeping can lengthen the travel of the stone by 3 m. Suppose the stone is launched with a speed of 3 m/s and travels 40 m before coming to rest. What is the approximate magnitude of the friction force on the stone?A. 0 N B. 2 N C. 20 N D. 200 N
