A potato gun having a 0.560 m long barrel fires a 300 g potato by means of expanding gas. As the gas expands, the force on the potato is Fx = 14,500 N + (9000 N/m)x − (25,000 N/m2)x2, where x is in meters the x axis is along the lenght of the barrel. Determine the work done by the gas on the potato as it travels the length of the barrel.

d. learned preferences i believe is your answer

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
