After doing some research on Wiki, Google, and Easyscienceforkids, I have come to a conclusion that:
Mass: 5.972 * 10^24 kg
Radius: 3958.8 mi
Distance from the sun: 92.96 million mi
Explanation:
Acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (7 m/s − 0.8 m/s) / 15 s
a ≈ 0.413 m/s²
Force on left crate, right crate and truck we need to draw here
First we will write the equation for left crate
Now similarly for right crate
now for truck
Now we know that F = 200 N
now add all three equation
now we will find all tension using this value of acceleration
When we hit the puck from tap the puck will move forward.
This is due to the impulse provided by us at the time of hit. Due to this impulse the puck will move forward and start moving in some direction.
As soon as puck move forward the force on it is zero as the weight of the puck is counterbalanced by the air stream force and there is no other force on it so puck will continue its motion till it will hit at some other point.
So here the motion of the puck will be uniform motion till it will collide with some other points.
So here the correct option will be given as
<em>moves with a constant speed until hitting the other end.</em>
