Answer:
v = 0.028 m/s
Explanation:
In this case you take into account that all the elastic potential of the box, when the spring is compressed is equal to the kinetic energy of the box before it hits the spring. That is:
(1)
m: mass of the box = 4.5kg
k: spring constant = 85N/m
x: compression of the spring = 6.5cm = 0.0065m
You solve the equation (1) for v:
(2)
Next, you replace the values of the parameters:
The velocity of the box when it hits the spring is 0.028m/s
