Find the amplitude, angular frequency, frequency and period of motion for an object vibrating at the end of a horizontal spring if the equation for its position as a function of time is x = (0.25 m) cos((π/8)×t)

Find the maximum magnitude of the velocity and acceleration.
What is the position, velocity and acceleration of the object after 1.0 s has elapsed?​

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
