Weathering and rock slides
K.E. = 1/2 mv²
K.E. is directly proportional to v^2
So, when K.E. increase by 2, K.E. increase by root. 2
v' = 1.41v
original v value was 3 so, final would be:
v' = 1.41*3 = 4.23
After round-off to it's tenth value, it will be:
v' = 4.2
So, option B is your answer!
Hope this helps!
d =2.55.68m and t = 11.36s
In my opinion
Add them together with south being negative. (-350 + 25) to get 325 south
Answer:No,a smaller object would have more acceleration because it would take less force to move.
