The function sequalst cubed minus 6 t squared plus 12 t, 0 less than or equals t less than or equals 3, gives the position of a body moving on a coordinate line, with s in meters and t in seconds. a. find the body's displacement and average velocity for the given time interval.

What is the momentum of a 2 kg object moving at 15 meters per second

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

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
