An old truck compresses a spring scale at the junkyard by 25 cm. the spring constant for the industrial scale at the junkyard is 39,200 n/m. what is the force applied to the scale by the car?

Force, F = 9800 N

Explanation:

It is given that,

The spring constant for the industrial scale at the junkyard is, k = 39,200 N/m

The compression in the spring, x = 25 cm = 0.25 m

To find,

The force applied to the scale by the car.

Solution,

The Hooke's law gives the relation between the force and the compression in the spring. Its expression is given by :

F = 9800 N

So, the force applied to the scale by the car is 9800 N.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
