Answer: The kinetic energy for the car in motion is E k = 320,000 J = 32,000 kg m 2 /s 2 . Let's say that for a particular wave on a string the equation is: y(x,t) = (0.9 cm) sin[(1.2 m-1)x - (5.0 s-1)t] (a) Determine the wave's amplitude, wavelength, and frequency. (b) Determine the speed of the wave. (c) If the string has a mass/unit length of m = 0.012 kg/m, determine the tension in the string. v = 486.8 m/s Here is the above set-up done with units: v = [(3) (8.31447 kg m 2 s-2 K-1 mol-1) (304.0 K) / 0.0319988 kg/mol.
So 1 kilojoules = 10 3 joules.
In our example, lifting a weight straight up, the acceleration we're fighting is due to gravity, which equals 9.8 meters/second 2. Calculate the force required to move our weight upward by multiplying (10 kg) x (9.8 m/s 2) = 98 kg m/s 2 = 98 Newtons (N). If the object is being moved horizontally, gravity is irrelevant.
