A 0. 20-kg ball is attached to a vertical spring. the spring constant is 28 n/m. when released from rest, how far does the ball fall before being brought to a momentary stop by the spring?

Answers

A 0. 20-kg ball is attached to a vertical spring. The spring constant is 28 n/m. when released from rest, the ball will fall at a distance of x = 0.14 m   before being brought to a momentary stop by the spring.

The spring constant is the force needed to stretch or compress a spring, divided by the distance that the spring gets longer or shorter. It's used to determine stability or instability in a spring

Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.

When ball is released from rest with spring , it will loose some potential energy . Hence , loss in potential energy of the ball = gain in potential energy of spring

m*g*x = 1/2 * k * [tex]x^{2}[/tex]

0.20 * 9.8 * x = 1/2 * 28 * [tex]x^{2}[/tex]

x = (2 * 0.20 * 9.8) / 28

A wave of wavelength 1.2m travels 11.2m to a wall in 2s. what's the frequency of the wave

Answers

Answer: f = 4.67 Hz

Explanation:

We can approximate the wave as a traveling wave, therefore the speed of the wave is constant         

v = d / t

the total distance remember, in going to the wall and back is         

d = 2 11.2 = 22.4 me

we substitute         

v = 22.4 / 4.0          

v = 5.6 m / s

now we can use the relationship between the speed of the wave, its wavelength and u frequency          

v =λ f         

f = v /λ       

f = 5.6 / 1.2        

f = 4.67 Hz

Two forces produce the same torque. does it follow that they have the same magnitude?

Answers

Two forces produce the same torque but this will not ensure that they have the same magnitude of torque because torque is the product of force times distance.

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Torque is a vector quantity.

The physical quantities for which both magnitude and direction are defined distinctly are known as vector quantities. For example, a boy is riding a bike with a velocity of 30 km/hr in a north-east direction.

The quantity torque (or moment of force) may be thought of as the cross product of force and distance and the SI unit for torque is Newton metre, N m (m2 kg s-2).

No, Because torque is the product of force times distance, two different forces that act at different distances could still give the same torque.

Work is said to be positive when Kinetic energy is greater than velocity (option B). Details about work can be found below.

Work is a measure of energy expended in moving an object; most commonly, force times distance. This means that no work is done if the object does not move.

However, work can either positive or negative depending on the direction of the object and the force applied.

When force and displacement are in the same direction, the work performed on an object is said to be positive work.
