Answer: 18.56 m/sec
Explanation:
Average velocity =distance/time=5400/(4.85*60)=18.56 m/sec
Answer:
A., B. & C.
Explanation:
All apply, because all these happen in a plant.
I can't decide between A and B, but B seems more likely to me. Even though the molecules don't look like they're moving, the area of contact is slightly more compressed.
initial velocity of the car given as

final velocity is given as

as we know that

now we can convert final speed into m/s

now acceleration is rate of change in velocity



so the acceleration of the car is 3 m/s^2
