I'm using the equation T= 2 pi square root of (L/G) and I don't know what I'd do with the horizontal acceleration. Because for vertical accleration I just added to G like 9.8 + 2.00 m/s^2 or 9.8 - 2.00 m/s^2 and that was correct for my other two parts of the problem. The mass is not supposed to have anything to do with the problem I guess.berkeman said:Well don't just add or subtract. How do the directions of the accelerations affect the pendulum mass? What determines the motion of a pendulum mass?
No, just whatever I posted above is what he gave us. What do you mean by "canned"?berkeman said:Did your instructors (or the textbook) give you the derivation of the "canned" pendulum oscillation equations? This question may be kind of hard to address without the basic equations...
Often in physics classes, you will be given a formula to apply. But when you are given a different setup or initial conditions or situation, the canned formula will not apply. That is when you need to go back to the original derivation to figure out the answer for the new problem statement.lydster said:No, just whatever I posted above is what he gave us.

I asked you if the REST frame of the truck was an INERTIAL frame.lydster said:I don't know if it's an internal frame.
Yes the pendulum is hanging straight down, because we're assuming again that it starts from rest.
A simple pendulum is a mass (usually a bob or weight) attached to a fixed point by a string or rod. It is a classic example of a harmonic oscillator and exhibits regular periodic motion.
A simple pendulum in a moving truck will still exhibit regular periodic motion, but its period will be affected by the truck's motion. As the truck accelerates or decelerates, the pendulum will experience an additional force, causing its period to change.
The period of a simple pendulum in a moving truck is affected by the truck's acceleration, the length of the pendulum, and the force of gravity. Additionally, air resistance and the angle of the pendulum's swing may also have an impact.
The period of a simple pendulum in a moving truck will decrease as the truck's speed increases. This is because the pendulum's motion is affected by the truck's acceleration, and the faster the truck moves, the more force is applied to the pendulum, causing it to swing faster and thus decreasing its period.
The period of a simple pendulum in a moving truck can be calculated using the equation T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity. However, this equation may need to be adjusted to account for the truck's motion and any other factors that may affect the pendulum's period.
