# When a 2.50 kg object hung ver

When a 2.50 kg object hung vertically on a certain light spring described by Hooke’s law, the spring stretchex 2.76 cm (0.0276m) What is the spring constant of the spring? (Use f=KX you will have to find the force that gravity on the object!) b. If the 2.50 kg object is removed, how far will the spring stretch if a 1.25kg block is hung on it.  (the spring constant will be the same) How much potential energy in the spring when it stretched 4 cm?

A mechanic pushes a 2.50*10^ 3 kg car from rest to a speed of vThis required 5,000 J of energy. During this time, the car moves 25.0 m. a. Neglecting friction between car and road, find y b. If the mechanic moved the car from rest to a speed of much energy would be required?
