Question

Solve each problem using proper problem solving format. (A) Two masses of 2000 kg each are located a distance of 0.500 m apart. (a) What is the magnitude of the gravitational force one mass experiences from the other mass? (b) What is the gravitational potential energy of this two mass system? (B) A pendulum oscillates with a frequency of 1.25 Hz. What is the length of the pendulum? (C) A traveling wave is described by the equation y = 0.400 sin (10.0x + 12.0 t). x and y are in meters and t is in seconds. (a) What is the amplitude of the wave? (b) What is the frequency of the wave? (c) What is the wavelength? (d) What is the speed of the wave? (e) What direction is the wave traveling?

Explanation / Answer

1) A) a) F = Gm1m2 / r^2

= 6.67*10^-11 * 2000*2000 / 0.5^2

=0.0010672 N

b) U = Gm1m2 / r = 6.67*10^-11 *2000*2000 / 0.5 = 5.336*10^-4 J

B) f = 1/2pi*sqrt(g/L)

1.25 = 1/2pi*sqrt(9.8/L)

L = 0.16 m
