A new event has been proposed for the Winter Olympics. An athlete will sprint 100 m, starting from rest, then leap onto a 20 kg

bobsled. The person and bobsled will then slide down a 50-m-long ice-covered ramp, sloped at 20 degrees , and into a spring with a carefully calibrated spring constant of 2000 N/m. The athlete who compresses the spring the farthest wins the gold medal. Lisa, whose mass is 40 kg, has been training for this event. She can reach a maximum speed of 12 m/s in the 100 m dash. How far x will Lisa compress the spring?

You are asked to design a spring that will give a 1160-kg satellite a speed of 2.50 m>s relative to an orbiting space shuttle
Maru [3345]
Given the values: m = 1160 kg g = 9.81 m/s² v = 2.5 m/s Unknowns include: k (spring constant) x (spring compression) 1. To address this, use Newton's second law and Hook's law: 2. The total energy in the spring must correspond to the satellite's energy: By combining these two equations
