If a train travelled 500 meters in 25 seconds then,
Speed = 500m/25sec
<h2>→ 20 m/sec</h2>ANSWER:
250 J
STEP-BY-STEP EXPLANATION:
F = 20N is required to stretch the spring by 4 meters
We know that the force is equal to:
We solve for k (spring constant):
The work done in stretching the spring is given by the following equation (in this case the stretch is 10 meters:
The work required is 250 joules.
