More than five million cubic kilometers of ice have been identified.
(a) Her distance from the starting location is 21.05 m.
(b) The length of the path she skated is 21.05 m.
<h3>
Distance of the skater from the starting position</h3>
The distance around a complete circular path is calculated as 2πr.
The distance for a half circle is calculated as ¹/₂ x 2πr = πr
Distance from the starting location = π x 6.7 m = 21.05 m
The length of the path she skated is the same as her distance from the starting location = 21.05 m.

Answer:
the inertia provides the tendency to maintain speed and keep moving
Answer:
F = 3.20 N
Explanation:
Given:
Work done by child = 80.2 j
Distance that the car moves = 25.0 m
We need to find the force acting on the car.
Solution:
Using work done formula as.
Where:
W = Work done by any object.
F = Force (push or pull)
d = distance that the object moves.
Substitute 
in work done formula.
F = 3.20 N
Therefore, force acting on the car F = 3.20 N
