The cart is moving by simple harmonic motion, and its position at time t is described by
where
A is the amplitude of the oscillation
is the angular frequency
The amplitude of the oscillation corresponds to the maximum displacement of the spring, which corresponds to the initial position where the spring was released:
A=0.250 m
The period of the motion is T=5.67 s, and the angular frequency is related to the period by
Therefore now we can calculate the position of the system at the time t=29.6 s:

The ratio between power of A and power of B is 2
Explanation:
In physics, power is defined as the ratio between the work done and the time taken to do the work:
where
P is the work done
t is the time taken
In this problem, we have:
Person A and person B do the same amount of work --> let's call this work W
Person A does this work in a time of , so the power delivered by A is
Person B does this work in a time of , so the power delivered by B is
So, the ratio of the powers delivered by the two persons is

Answer:
Negative
Positive
Explanation:
When a positive charge balloon is brought near the neutral metal can, the positive charge in the ballon, delocalization and arrangement of like charges occurs. The positive charge then flow to the an end while the negative charges flows to the other end.
Thus, after being touched, the charge on the can is negative.
And, If not touched, the charge on the ballon remains positive.
