A 0.23 kg mass on a spring vibrates with amplitude 25 cm and frequency 1.7 Hz. Calculate (b) the speed at which the mass passes through equilibrium and (b) the total energy of the oscillation. (Answers: 0.82 J, 2.7 m/s).

a) 2.67 m/s

b) 0.82 J

Explanation:

Amplitude A = 25 cm = 0.25 m

The period of the motion is the inverse of the frequency

So the angular frequency

The speed at the equilibrium point is the maximum speed, at

The spring constant can be calculated using the following

The total energy of the oscillation is

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
