Answer:
0.392
Explanation:
Mm = 0.11Me
Rm = 0.53Re
g = GM / r^2
G = 6.67 * 10^-11
gmars = (G * 0.11Me) / (0.53Re)^2
Recall:
gearth = GMe /Re^2
Hence, gmars in terms of gearth equals
gmars = gearth * (0.11 / 0.53^2)
gmars = gearth * 0.3915984
gmars = 0.392gearth

Technically, you can simply point out that "acceleration" MEANS
"change in velocity", so of course they have the SAME direction.</span>
Answer:
Approximately 8 seconds (which seems to be Answer B although there is a typo)
Explanation:
Use the formula that defines acceleration of an object as the difference between its final velocity and its initial velocity divided by the time it took to go from one to the other:
We use this expression and the values given to solve for the unknown "t" (time):
Given the units of the physical quantities, the answer for t is in seconds. We round it to about 8 seconds.
Answer:
The centripetal acceleration of the rock is 10.7 m/s^2, towards the centre of the circle
