5. During the annual shuffleboard competition, Renee gives her puck an initial speed of 9.32 m/s. Once leaving her stick, the puck slows down at a rate of - 4.06 m/s/s. Determine the time it takes the puck to slow to a stop.

An ideal gas is held in a canister of volume V, at pressure P, and temperature T. Subsequently, the movement of a piston doubles the volume (to 2 V), while the temperature is also doubled (to 2 T), in absolute units (e. g. Kelvin).

A 3.70 kg block moving 2.09 m/s right hits a 2.42 kg block moving 3.92 m/s left. Find the total momentum of the system.

Two masses are separated by 1 m. suppose the masses are moved so they are 2 m apart how will the gravitational force change
