A 51 g object is definitely attached to a horizontal

springtime with a spring constant of 14. 5 N/m

and released via rest with an amplitude of

27. 2 cm.

What is the speed of the subject when it

is halfway for the equilibrium situation if the

surface is frictionless?

Explanation:

Let: m = 51 g = 0. 051 kg,

k = 14. 5 N/m, and

A = 27. 2 cm = 0. 272 m.

008 (part 1 of 2) 10. zero points

A 0. 34 kg thing is attached with a springtime with

a spring continuous 171 N/m so that the object

is in order to move on a horizontal frictionless

surface. The object is produced from relax when

the spring is compressed 0. 11 meters.

Find the force on the object.

010 (part one particular of 4) 10. 0 points

A 0. thirty-one kg target connected to a mild spring

using a spring constant of nineteen. 1 N/m oscillates on the frictionless side to side surface. The spring is usually compressed eight. 8 cm and introduced from

snooze.

What is the maximum speed in the mass?

Correct answer: zero. 690746 m/s.

Explanation:

Presented:

m = 0. 31 kg,

t = nineteen. 1 N/m, and

A = eight. 8 cm = 0. 088 m.

Correct answer: 18. 81 N.

Reason:

Applying conservation of mechanical energy,

Allow: m = 0. thirty four kg,

e = 171 N/m,

back button = −0. 11 meters.

and

The force exerted on the block by spring

is definitely

Precisely what is the speed from the object when the

spring is definitely compressed 1 . 8 cm?

Correct solution: 0. 676142 m/s.

Explanation:

Given:
