Iodine, chloride, and bromide
Answer:
a. 6.41 m/s
b. 120.85 m/s^2
Explanation:
The computation is shown below:
a. Pebble speed is
As we know that according to the tangential speed,
= 6.41 m/s
The 18.84 come from
= 18.84
b. The pebble acceleration is
= 120.85 m/s^2
We simply applied the above formulas so that the pebble speed and the pebble acceleration could come and the same is to be considered
Force = mass • acceleration
1) Find acceleration
-) 8kg ball
a= v/t
a= .2/ 10 = .02 m/s^2
Force = 8kg • .02 = .16N
-) 4kg ball
a= v/t
a= 1.0/ 10 = .1 m/s^2
Force = 4kg • .1 = .4N
Answer: The 8kg ball would need more force because it requires .16N, while the 4kg only need .4N .
^they’re correct! it is weathering, i just took a test with that answer:)
