Amass hanging from a spring undergoes vertical simple harmonic motion.1) where in the motion is the velocity equal to zero? at the point where the spring is unstretched. at the highest point in the oscillation. at the lowest point in the oscillation.

At the highest point and at the lowest point the velocity of the mass hung on a spring = 0

Explanation:

Simple Harmonic Motion ( S.H.M) : Simple harmonic motion can be defined as a type of motion were a body vibrates or moves to and fro along a straight line under the influence of a force, so that the acceleration of the body towards a fixed point (equilibrium position) is proportional to its distance or displacement from that point. Examples of  bodies undergoing simple harmonic motion are

⇒ The motion of a mass hung on a spring.

⇒ The motion of a simple pendulum

⇒ The motion of a loaded test - tube in a liquid.

Motion of a mass hung on a spring:When a mass is hung to one end spring and other end is firmly clamped to a rigid support.(i)When the mass is in motion, (ii)it pulled down to its lowest point, passes through it equilibrium position (iii) goes to its highest point.

(1) At the lowest and the highest point during the motion of a mass hung a spring, the velocity = 0

(2) At the equilibrium point or unstretched position the velocity is maximum

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
