Answer:B
Explanation:
Given
speed of car 
mass of clump 
Radius of car tire 
Since the tire is rotating about axle so a centripetal force is acting constantly on each particle towards the center of tire.
Centripetal force is given by
where 
(inward)
Friction I believe is the answer
hope this helps
Answer: d = 400 m
Explanation:
Distance during acceleration
d = ½at² = ½(2.0)10² = 100 m
velocity after 10 s
v = 2.0(10) = 20 m/s
distance at constant speed
d = vt = 20(10) = 200 m
As the acceleration is the same magnitude while slowing down as speeding up, It will take the same distance to complete the deceleration 100 m
Total distance is 100 + 200 + 100 = 400 m
If your seeing this good luck and Have a great dayyy!
Answer:
where is volume? formula of density is: mass/volume so volume must be there
