Answer:
0.130
Explanation:
From the given data, the coefficient of static friction for each trial are:
1. 0.053
2. 0.081
3. 0.118
4. 0.149
5. 0.180
6. 0.198
The sum of the coefficient of static friction = 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198
= 0.779
So that;
the average coefficient of static friction = 
= 
= 0.12983
The average coefficient of static friction is 0.130

Answer:
Total distance does the grasshopper travel before the cars hit is 150 m
Explanation:
Each car moves x=100 m before they collide. Both the cars moving in constant velocity. time taken t by each car is

where x is the distance traveled with velocity v

The insect is moving through this time period with a constant velocity of 15 m/s
The distance traveled by grasshopper is

funny of u to assume I have friends
If I remember anything from that part of my education (not great at physics) I'd say the answer is A, though I admit i'm not 100% sure
I dunno how to explain, once it hits that's the energy that was converting I guess.
