Answer:
average acceleration is 1.365 ×
m/s²
Explanation:
given data
initila speed u = -32.2 m/s
final speed v = 21.6 m/s
time taken t = 0.00394 s
solution
we get here average acceleration that will be express as
v = u + at ..........................1
put here value and we get
21.6 = -32.2 + a × 0.00394
solve it we get
a = 1.365 ×
m/s²
so average acceleration is 1.365 ×
m/s²
So basically the objects would be sandpaper and smooth metal, the sandpaper can indirectly touch the metal since it’s so smooth and it won’t cause any temp change either
I think the answer is Gamma Rays
Answer: A. Her speed is 4.4 m/s, and her velocity is 0 m/s.
