While merging in traffic, a driver increases her speed from 10 m/s to 20 m/s. What is the resulting change in the car's kinetic energy?

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
