On a spacecraft, two engines are turned on for 789 s at a moment when the velocity of the craft has x and y components of v0x = 5410 m/s and v0y = 8100 m/s. while the engines are firing, the craft undergoes a displacement that has components of x = 2.78 x 106 m and y = 4.73 x 10^6m. find the (a) x and (b) y components of the craft's acceleration.

Explanation:

Given

time for which spacecraft turned on is 789 s

we know

For y component

d. learned preferences i believe is your answer

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
