A0.750kg block is attached to a spring with spring constant 13.5n/m . while the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 32.0cm/s .

what are :

a) the amplitude of the subsequent oscillations?
express your answer with the appropriate units.

b) the block's speed at the point where x= 0.750 a?
express your answer with the appropriate units.

A)A=0.075 m

B)v= 0.21 m/s

Explanation:

Given that

m = 0.75 kg

K= 13.5 N

The natural frequency of the block given as

The maximum speed v given as

A=Amplitude

A=0.075 m

A= 0.75 cm

The speed at distance x

v= 0.21 m/s

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
