Explanation:
In this problem we have to draw a velocity-time graph for an object travelling initially at -3 m/s, then slowing down and turning around.
In the graph, we see that the initial velocity at time t = 0 is
and it is negative, so below the x-axis.
Later, the object slows down: this means that the magnitude of its velocity increases, therefore (since the velocity is negative) the curve must go upward, approaching and reaching the x-axis (which corresponds to zero velocity).
After that, the object's velocity keep increasing, but now it is positive: this means that the object is travelling in a direction opposite to the initial direction, so it has turned around.

Answer: Correct answer is B = 1.776933×
Explanation:
Given :
Moment of inertia I = 8.26× kg
Mass of planet m = 6.54× kg
Also, Planet is solid sphere so that, Moment of inertia is I = m
=0.4m
Where R is radius of planet
Putting into calculation
We get,
I = m
8.26× = 0.4×6.54×
×
8.26× = 2.616
3.15749235× =
R = 1.776933×
Thus, Correct answer is B = 1.776933×
