If a dog has a potential energy of 1500 J and a mass of 24 kg, how high off the ground is he?

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?

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.

The first law of thermodynamics is as follows: ∆u=q-w , which means in a system is equal to added, minus done by the system. the units for these variables are in .
