There is a 1.75 kg mass oscillating as a function of time, according to this exact equation x = 4 cos(1.33t+/5). The displacement of the variable x is measured in meters and time t in seconds. Answer the following: - Find the amplitude, frequency, period of motion, and angular frequency. - Write the equation for the velocity of the particle. - Write the equation for the acceleration of the particle. - What would be the constant of the spring if the oscillation was caused by a spring attached to the mass?
