A car weighing 12000 N is parked on a 36° slope. The car starts to roll down the hill. What is the acceleration of the car??

Can you receive a shock severe enough to prevent you from releasing the wire from an ordinary outlet with dry hands? a. no b. yes explain

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?

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
