presents a model for solving this problem. As far as vertical oscillations are concerned, a certain automobile can be considered to be mounted on four identical springs, each having a spring constant of 1.28 x 105 N/m. Then, four identical passengers are seated in the car, and it is set into a vertical oscillation that has a period of 0.387 s. If the mass of the empty car is 1560 kg, determine the mass of each passenger. Assume that the mass of the car and its passengers is distributed evenly over the springs.

A mass of 16 kilograms is suspended from a spring with spring constant 7 Kg/sec^2. The damping constant is 2 Kg/sec and the spring is subject to an external force F(t)= 3cos(9t) Newtons. The motion of the mass eventually settles down to a periodic oscillation. What is the period (in sec) of this periodic oscillation? 2 9.

A (12.6 + A) g mass is hung on a string with a length of (68.4 + B) cm. The mass is then pulled back until the string makes a (5.00 + C/10) degree angle from the vertical and released. Find the period of the pendulum. Give your answer in seconds (s) and with 3 significant figures. A=20 B=78 C=8

A patio swing is suspended by two springs, each of which has a force constant of 430 N/m, equivalent to a single spring force constant of 860 N/m. Find the mass of a person sitting on the swing oscillating up and down at a frequency of 0.595 Hz.

A cart of mass 206 g is placed on a frictionless horizontal air track. A spring having a spring constant of 10.80 N/ m is attached between the cart and the left end of the track. When in equilibrium, the cart is located 10.0 cm from the left end of the track. If the cart is displaced 5.10 cm from its equilibrium position, find(a) the period at which it oscillates   A cart of mass 206 g is placed on a frictionless horizontal air track. A spring having a spring constant of 10.80 N/ m is attached between the cart and the left end of the track. When in equilibrium, the cart is located 10.0 cm from the left end of the track. If the cart is displaced 5.10 cm from its equilibrium position, find (d) its speed when it is 12.0 cm from the left end of the track.

A 50 cm long spring with spring constant 257 N/m has a mass 1.9 kg attached to it, and it can oscillate on a horizontal table without any friction. When the spring is pulled so that its length is 55 cm, what is the magnitude of the maximum acceleration of the mass? Give your answer in m/s?.

A vertical spring scale can measure weights up to 170 N . The scale extends by an amount of 11.5 cm from its equilibrium position at 0 N to the 170 N mark. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.05 Hz . Ignoring the mass of the spring, what is the mass m of the fish?

Astronauts in space cannot weigh themselves by standing on a bathroom scale. Instead, they determine their mass by oscillating on a large spring. Suppose an astronaut attaches one end of a large spring to her belt and the other end to a hook on the wall of the space capsule. A fellow astronaut then pulls her away from the wall and releases her. The spring's length as a function of time is shown in the figure (Figure 1). Figure L (m) 1.4 1.2 1.0 0.8 0.6 0.4- 0.2 0.0 0 3 < v 6 1 of 1 -t (s)

Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s not cm/s). Answer must be in standard form scientific notation. All angles are to be calculated to the nearest 0.1 deg (tenth of a degree).
