A body of mass 100 gm is suspended vertically in a spring. If the spring is withdrawn and left to move a simple harmonic motion, it can make 1200 revolutions within a time of 5 min. Calculate: 1- The frequency of the spring 2- The constant of the spring. 3- If the spring is replaced by the last constant of the spring, which has four times the original pulsator, the cyclical time will be HELP ASAP PLZZ GUY

What is the measurement of how fast an object moves relative to a reference point?

Frank just graduated from eighth grade. assuming exactly four years from now he will graduate from high school how many seconds does he have until his high school graduation

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
