We know that centripetal acceleration is nothing but the ratio of the square of the tangential velocity to that of the radius vector.
a=v*v/r=ωωrr/r
=ωωr
=2πf2πfr
=2π2πr/TT
=97m/secsec
Hi there!
We know that:
U (Potential energy) = mgh
We are given the potential energy, so we can rearrange to solve for h (height):
U/mg = h
g = 9.81 m/s²
m = 30 g ⇒ 0.03 kg
0.062/(0.03 · 9.81) = 0.211 m
C.
With choice A - you can choose if you are being lazy. Choice B there are options to help control or manage stress. And choice D you are in control of if you have any conflicts with other workers.
Hope this helps.

Answer:
15Ns
Explanation:
Given parameters:
Mass of the object = 10kg
Force impact = 5N
Time of action = 3s
Unknown:
Impulse applied on the object = ?
Solution:
Impulse is the force that acts on object within a period of time.
Mathematically;
Impulse = Force x time
Now insert the parameters and solve;
Impulse = 5 x 3 = 15Ns
