Question: The spring shown in FIGURE P10.54 is compressed 50 cm and used to launch a 100 kg physics student. The track is frictionless until it

The spring shown in FIGURE P10.54 is compressed 50 cm and used to launch a 100 kg physics student. The track is frictionless until it starts up the incline. The student??s coefficient of kinetic friction on the 30? incline is 0.15.

k= 80,000 N/m m= 100 kg 10 m 30 FIGURE P10.54 a. What is the student??s speed just after losing contact with the spring?b. How far up the incline does the student go?

k= 80,000 N/m m= 100 kg 10 m 30 FIGURE P10.54
