Ayuda con este problema de fisica por es urgente dos ciclistas se mueven de tal forma que sus posiciones vienen dadas por: xa, xb. donde xa= -5t + 3. y xb= 6t - 4 xa y xb son las pocisiones de los ciclistas en cada intervalo de tiempo: responde a) cuanto tiempo tardan los ciclistas en encontrarse? b) cuanto tiempo ha pasado antes de que los ciclistas esten separados 50 metros?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
