b. The block's speed at the point where x= 0.750 A?

a. The amplitude of the subsequent oscillations?

b. The block's speed at the point where x= 0.750 A?

b. The block's speed at the point where x= 0.750 A?

Answer:

a

b

The value is

Explanation:

From the question we are told that

The mass is

The spring constant is

The instantaneous speed is

The position consider is x = 0.750A meters from equilibrium point

Generally from the law of energy conservation we have that

The kinetic energy induced by the hammer = The energy stored in the spring

So

Here a is the amplitude of the subsequent oscillations

=>

=>

=>

Generally from the law of energy conservation we have that

The kinetic energy by the hammer = The energy stored in the spring at the point considered + The kinetic energy at the considered point
