Velocity = displacement/time
1.6 = 253/t
t = 158.125
It takes them about 158 seconds
The elastic potential energy stored in the stretched spring is 1 J.
<h3>What is Hooke's law?</h3>
Hooke's law states that; provided the elastic limit is not exceeded, the extension of the spring is directly proportional to the force on the spring.
Given that;
Force on the spring = 350 Newton
Distance stretched = 7 centimeters or 0.07 m
Hence;
F = ke
k = F/e = 350 Newton/0.07 m = 5000 N/m
Work done in stretching a spring = 1/2ke^2
= 0.5 × 5000 × (2 × 10^-2)^2 =1 J

It's cold outside, the water vaper in your breath condenses into tiny droplets of liquid water and ice that you can see.
Middle school? lol but, the third one.
