Question

I do not know how to find the work in 3(c) since I don't know the force. Help please.

K: 500 N/m Ax= 3meters MK = 0.3 Ax 10 metてry Imeters 50° 9. 3) The 15 kg object starts at rest. The spring is compressed 3 meters. Calculate the speed os the object at point "a", where all of the springs potential energy the 7s Kg objects Kinetic eneryy. has been converted to Calculate the speed of the object after it has slid down a ramp (no Sriction) 1 meters. Calculate how much negative work the grass does on the s Kg object, What is the speed of the object after the grass? Have the 15 kg object do one more task! It can go up a hill, down a hill, hit a spring (if so, calculate how Jar the spring compresses until the object stops), or across some grass. Use two decimal places, so that your task is unique ! 3.
