Answer:
Explanation:
By using the Newton second law and the position equation for a simple harmonic motion we have

where a is the acceleration, w is the angular frecuency and \phi is the phase constant. We can calculate w from the equation for the maximum acceleration

(a).

(b). 
(c). 
(d). The mecanical energy is the kinetic energy when the velocity is a maximum

Answer:
225 N
Explanation:
Force = Mass . Acceleration
F = 45 . 5
F = 225 N
Answer:
2.66 m/s² .
Explanation:
Initial velocity , u = 0 m/s
Final Velocity , v = 8 m/s
Time Taken , t = 3 s
So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²
