Potential Energy/ Spring Problem?

The four wheels of a car of mass 1200kg are suspended below the body by vertical springs of constant k 65000 N/m.If the forces on all wheels are the same, what will be the maximum deformation of the springs if the automobile is lifted by a crane and dropped from a height of 0.80m(measured from cars center of gravity.) I know this problem has something to do with U.5kx^2 but I am having trouble getting the right answerAny help outlining the steps is appreciated.

Answer:

Crispy Crunchy Chicken Bites Sesame seeds and oil traditionally are associated with Hanukkah, and this recipe combines themThey make a nice appetizer, and I also enjoy them over a green salad with orange sections Serving: 6 Prep Time: 25 minutes Cook Time: 15 minutes Total Time: 40 minutes 2 cloves minced garlic 1 tablespoon minced fresh ginger 1 tablespoon freshly squeezed lemon juice 1 tablespoon soy sauce 1 pound boned and skinned chicken breasts 1/2 cup apricot preserves 1 teaspoon dry mustard 1 teaspoon boiling water 1 tablespoon freshly squeezed lemon juice 3/4 cup finely ground blanched almonds 1/4 cup sesame seeds 2 cups vegetable oil 1Mix the garlic, ginger, lemon juice and soy sauce in a large, sturdy, sealable plastic bagSlice the chicken breasts into one-inch slicesPlace the chicken in the marinade and refrigerate over night 2Melt the apricot preserves in a small saucepan until smoothIn a small serving bowl, mix the mustard and hot water until smoothBlend the apricots and lemon juice into the mustard mixture and garnish, if desiredSet aside to cool 3Mix the ground almonds and sesame seedsHeat about two inches of the oil over medium heat in a large skillet to about 350 degreesDip the chicken pieces into the almond-sesame mixture and deep fry several at a time until golden brown on each side, about one minuteIf they brown too fast, remove the skillet from the heat for a few minutes and reduce the heatDrain the chicken thoroughly on paper towels before serving hot with the dip.
