Hit is the action for the movement
Answer:

Explanation:
From the question, acceleration from
in 10 seconds.
Acceleration function can be written as:-

From the acceleration equation, we can obtain the velocity equation:

We calculate velocity after 10sec from the above v(t) as
.
To obtain distance travelled after 10 seconds:-

Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
A 300-kg bear grasping a vertical tree slides down at constant velocity. The friction force between the
tree and the bear is
In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
