Answer:
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
<em>⇒ The motion of a mass hung on a spring.</em>
<em>⇒ The motion of a simple pendulum</em>
<em>⇒ The motion of a loaded test - tube in a liquid.</em>
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.
<em>(1) At the lowest and the highest point during the motion of a mass hung a spring, the velocity = 0</em>
<em>(2) At the equilibrium point or unstretched position the velocity is maximum</em>
<em></em>
<em></em>
A wave that is traveling fast can be said to have a high speed.<em> (b) </em>
Just like a car, motorcycle, or freight train that is traveling fast.
Explanation:
Initial speed of the rocket, u = 0
Acceleration of the rocket, 
Time taken, t = 3.39 s
Let v is the final velocity of the rocket when it runs out of fuels. Using the equation of kinematics as :
Let x is the initial position of the rocket. Using third equation of kinematics as :
Let 
is the position at the maximum height. Again using equation of motion as :
Now 
and v and u will interchange
x = 524.14 meters
Hence, this is the required solution.
