The instruments attached to a weather balloon have a mass of 5 kg. the balloon is released and exerts an upward force of 106 n on the instruments. the acceleration of gravity is 9.8 m/s 2 . what is the acceleration of the balloon and the instruments? answer in units of m/s 2

How is zig zagging a form of acceleration?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver
