Answer:
Speed=1.633 m/s
Force= 20 N
Explanation:
Ideally, hence
where v is the speed of collar, m is the mass of collar, k is spring constant and s is the displacement.
In this case, s=100-0=100mm=0.1m since 1 m is equivalent to 1000mm
k is given as 200 N/m and mass is 0.75 Kg
Substituting the given values
Therefore, <u>the speed is 1.633 m/s</u>
The sum of vertical forces is given by mg where g is acceleration due to gravity and it's value taken as
Therefore,
The sum of forces in normal direction is given by therefore
Therefore, <u>normal force on the rod is 20 N</u>
