Answer:
a = 156.14 m/s^2
Explanation:
Using the laws of newton:
∑F = ma
where ∑F is the sumatory of forces, m the mass and a the aceleration.
so:
F -
= ma
where F is the force from the hockey stick and
is the force of friction.
Replacing values, we get:
(30.2N) - (3.5N)= (0.171kg)a
Finally, solving for a:
a = 156.14 m/s^2
Answer:
C and D
Explanation:
Charge on right = +0.001 C
Charge on left = 1000 C
Charge held in between = -1C
Ratio between right and left charge:

Which shows charge on left exerts 1,000,000 times more force then charge on right
Charge on left is 1000 times greater in magnitude than charge held between and charge held between is 1000 times greater in magnitude than charge on right. So the magnitude of the force on the charge you are holding would be the same if it were +1 C instead of −1 C.
