Ablock of ice accelerates and two meters per second dies has mass of 2 kilograms what is the size force it is acting on it

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)

1700 j of energy is lost from 0.14 kg object , the temperature decreases from 50°c to 45°c what is the specific heat of this object, amd what is the material ?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
