Chapter 4: Q. 4 (page 105)

Answer Problems 3 through 5 by choosing one of the eight labeled acceleration vectors or selecting option I:a→=0→

4. At this instant, the particle is speeding up and curving upward. What is the direction of its acceleration?

Short Answer

Expert verified

The direction of the acceleration of the particle at the given instant can be best describe with direction vector B.

Step by step solution

01

Step 1. Introduction

From the figure(I), the car is initially speeding up in the horizontal direction towards C, and then it is curving in the upward direction. Since the car is having positive velocity, so the car will have positive acceleration, directing toward the direction of its motion.

02

Step 2. Explanation

The following figure shows the direction of the acceleration of the particle at the given instant.

The acceleration vector of the particle at that instant can be best describe with the direction vector B.

Therefore, the direction of the acceleration of the particle at the given instant can be best describe with direction vector B.

You are target shooting using a toy gun that fires a small ball at a speed of 15 m/s. When the gun is fired at an angle of 30° above horizontal, the ball hits the bull’s-eye of a target at the same height as the gun. Then the target distance is halved. At what angle must you aim the gun to hit the bull’s-eye in its new position? (Mathematically there are two solutions to this problem; the physically reasonable answer is the smaller of the two.)

A turbine is spinning at 3800rpm. Friction in the bearings is so low that it takes 10min to coast to a stop. How many revolutions does the turbine make while stopping?

8. A particle's trajectory is described by x=12t3−2t2mand y=12t2−2tm, where t is in s.

a. What are the particle's position and speed at t=0sand t=4s?

b. What is the particle's direction of motion, measured as an angle from the x-axis, at t=0sand t=4s?

A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70 cm as she throws. She releases the javelin 2.0 m above the ground traveling at an angle of 30° above the horizontal. Top-rated javelin throwers do throw at about a 30° angle, not the 45° you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30° than they would be able to at 45°. In this throw, the javelin hits the ground 62 m away. What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration.

13. A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 100 m above the glacier at a speed of 150 m/s. How far short of the target should it drop the package?
