You are to build the oscillation transfer device shown in Fig. 15-27. It consists of two spring–block systems hanging from a flexible rod. When the spring of system 1 is stretched and then released, the resulting SHM of system 1 at frequency f 1 , oscillates the rod. The rod then exerts a driving force on system 2, at the same frequency f 1 . You can choose from four springs with spring constants k of 1600, 1500, 1400, and 1200 N/m, and four blocks with masses m of 800, 500, 400, and 200 kg. Mentally determine which spring should go with which block in each of the two systems to maximize the amplitude of oscillations in system 2. Figure 15-27 Question 10.

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.

A Use Kirchhoff's laws to calculate the currents through each battery and resistor in
terms of R1, R2, E1, & E2.
B Given that all the resistances and EMFs have positive values, if E₁ > E2 and R₁ > R2,
which direction is the current flowing through E₁? Through R₂?
C If E1 E2 and R₁ > R2, which direction is the current flowing through E₁? Through
R2?
A 105- and a 45.0-Q resistor are connected in parallel. When this combination is
connected across a battery, the current delivered by the battery is 0.268 A. When the
45.0-resistor is disconnected, the current from the battery drops to 0.0840 A.
Determine (a) the emf and (b) the internal resistance of the battery.

Initial circuit
A ball is shot at an angle of 60° with the ground. What should be the initial velocity of the ball so that it will go inside the ring 8 meters away and 3 meters high. Suppose that you want the ball to be scored exactly at the buzzer, determine the required time to throw and shoot the ball. Full solution and figure if there is.
