A3.95 kg mass attached to a spring oscillates with a period of 0.365 s and an amplitude of 19.0 cm.
(a) find the total mechanical energy of the system.
(b) find the maximum speed of the mass.

(a) 21.11 J

(b) 3.3 m/s

Explanation:

(a)

m = mass attached to the spring = 3.95 kg

A = amplitude of the oscillation = 19 cm = 0.19 m

T = Time period of oscillation = 0.365 s

U = Total mechanical energy

Total mechanical energy is given as

U = 21.11 J

(b)

v = maximum speed of the mass

maximum speed of the mass is given as

= 3.3 m/s

1= 26.17

2= 1.17

3=30.86

4=5.86
