M= 130 kg
v= 5 m/s
kinetik energy = ½• m•v²
= ½ • 130• 5²
= ½•130•25
= ½•3250
= 1625.
Answer:
For a given spring the extension is directly proportional to the force applied For example if the force is doubled, the extension doubles When an elastic object is stretched beyond its limit of proportionality the object does not return to its original length when the force is removed
