Answer:
The amount of potential energy that was initially stored in the spring is 88.8 J.
Explanation:
Given that,
Mass of block = 1.60 kg
Angle = 30.0°
Distance = 6.55 m
Speed = 7.50 m/s
Coefficient of kinetic friction = 0.50
We need to calculate the amount of potential energy
Using formula of conservation of energy between point A and B
Put the value into the formula
Hence, The amount of potential energy that was initially stored in the spring is 88.8 J.
Note that:
The electric field lines begin from the higher voltage to the lower, because the negative pole is lower voltage than the positive pole.
Thus, The lines go out the positive charges and go in the negative charges.
Also,
Like poles repel, unlike poles attract
<u>Then The correct figure is (A)</u>
