The acceleration is -1.111 m/s²
Explanation:
In this case acceleration is calculated as change in velocity divided by time.
Change in velocity is 20m/s-120 m/s = -100 m/s
Time is 1.5 minutes------change it to seconds by multiplying 1.5 by 60 seconds
Acceleration will be : -100 m/s / (1.5*60) = -1.111 m/s²

Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
The answer is silver. Silver is the most dense, it's a solid so it is more compact and is obviously the most likely to have more mass to it.
