3. A 2.75 kg particle moves as function of time as follows: x(t) = 5cos(1.25t+π/4); where
distance is measured in meter and time in seconds. (a) What is the amplitude, frequency,
angular frequency, and period of this motion? (b) What is the equation of the velocity of
this particle? (c) What is the equation of the acceleration of this particle? (d) What is the
spring constant? (e) What are the equations for the potential and kinetic energies of the
particle? (f) What is the total energy?

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
