The answer is B
because if you compare a regular road and ice... ice is smoother and therefore has less friction
Answer:
The motorcycle travelled 69.73 m during these 3.1 s.
Explanation:
In order to calculate the distance that the motorcycle travelled we first need to obtain the acceleration rate that was used to brake the vehicle. We do that by using the following formula:
a = (V_final - V_initial)/(t) = (15 - 30)/(3.1) = -4.84 m/s^2
The distance is given by the following formula:
S = (V_final^2 - V_initial^2)/(2*a)
S = (15^2 - 30^2)/[2*(-4.84)] = (225 - 900)/(-9.68) = -675/(-9.68) = 69.73 m
The motorcycle travelled 69.73 m during these 3.1 s.

Answer:
d=0.02m
Explanation:
The key of the exercise is to be able to graph the problem to be able to develop it. After that you simply proceed through a triangular relationship.
Then I leave the graph of the problem and give the solution.
So things, under the given relationship, we have,
<em>
*The value of 0.04 is taken because the triangle given in the graph must be divided in half, to obtain rectangular triangles.</em>
