First you need to find the initial x component which is 13.02. After that you plug it into the 3rd formula on the AP physics formula sheet. Then rearrange it into the quadratic formula and solve for time. The answer should be 4.1 seconds.

Electric discharge between two objects follows a predictable path?
LenaWriter [7]

Answer: YES

They always move towards the earth or any metallic conductor

Explanation:

Electric discharge between two objects follows a predictable path? YES

Static electricity is a buildup of electric charges on objects. Charges build up when negative electrons are transferred from one object to another. The object that gives up electrons becomes positively charged, and the object that accepts the electrons becomes negatively charged.

Once an object becomes electrically charged, it is likely to remain charged until it touches another object or at least comes very close to another object. That’s because electric charges cannot travel easily through air, especially if the air is dry.

They always move towards the earth or any metallic conductor

A hoop is rolling without slipping along a horizontal surface with a forward speed of 5.50 m/s when it starts up a ramp that mak
Burka [1]

Answer:

v_f = 4.22 m/s

Explanation:

As we know by energy conservation

initial total energy = final total energy

so we have

\frac{1}{2}mv^2 + \frac{1}{2}I\omega^2 = \frac{1}{2}mv_f^2 + \frac{1}{2}I\omega_f^2 + mgL sin\theta

so we have

v = R \omega

I = mR^2

mv_i^2 = mv_f^2 + mgL sin\theta

5.50^2 = v_f^2 + (9.81)(3) sin25

30.25 - 12.43 = v_f^2

v_f = 4.22 m/s
