Chapter 4: Q.9. (page 104)

An electromagnet on the ceiling of an airplane holds a steel ball. When a button is pushed, the magnet releases the ball. The experiment is first done while the plane is parked on the ground, and the point where the ball hits the floor is marked with an X. Then the experiment is repeated while the plane is flying level at a steady 500mph. Does the ball land slightly in front of the X (toward the nose of the plane), on the X, or slightly behind the X(toward the tail of the plane)? Explain.

Short Answer

Expert verified

one can conclude that the steel ball will land exactly on theX.

Step by step solution

01

Step.1.

After the button is pressed, the electro magnet releases the ball. This ball is projected with certain horizontal velocity and therefore it covers some horizontal distance, and finally strikes the ground. According to the given data, this striking point is marked as X.

In the first case, the plane is parked on the ground. In the second case, the plane is flying at 500 mph. The vertical motion of the plane will not affects the horizontal motion of the steel ball. As the horizontal; velocity of the steel ball in both the cases is same, it will still strikes the point X. Thus, one can conclude that the steel ball will land exactly on the X.

The angular velocity of a process control motor is ω=(20-12t2)rad/s, where t is in seconds.

a. At what time does the motor reverse direction?

b. Through what angle does the motor turn betweent=0s and the instant at which it reverses direction?

A circular track has several concentric rings where people can run at their leisure. Phil runs on the outermost track with radius rP while Annie runs on an inner track with radius rA = 0.80rP. The runners start side by side, along a radial line, and run at the same speed in a counterclockwise direction. How many revolutions has Annie made when Annie’s and Phil’s velocity vectors point in opposite directions for the first time?

22. II Susan, driving north at60  mph , and Trent, driving east at 45mph are approaching an intersection. What is Trent's speed relative to Susan's reference frame?

10. You have a remote-controlled car that has been programmed to have velocity , v→=−3ti^+2t2j^m/swhere t is in s. At ,t=0s the car is at r→0=(3.0i^+2.0j^)m. What are the car's (a) position vector and (b) acceleration vector at t=2.0s?

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.
