Hakeem has two objects that are different temperatures. the beginning temperature of object a is 10°c. the beginning temperature of object b is 29°c. he places the two objects so that they are in contact with each other. which diagram accurately shows the direction of heat flow in this scenario?

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
