at the top most point if Rupert will not fall then normal force at the top point is almost zero for minimum speed
so here we can say

now if





so above will be the minimum speed
(a) The y-component or vertical velocity is calculated using:
Vy = Vsin(∅)
(b) The x-component or horizontal velocity is calculated using:
Vx = Vcos(∅)
The si unit of force is newton.
so, F is eqal to m*g
Answer:
The acceleration of the mass is 2 meters per square second.
Explanation:
By Newton's second law, we know that force (
), measured in newtons, is the product of mass (
), measured in kilograms, and net acceleration (
), measured in meters per square second. That is:
(1)
The initial force applied in the mass is:


In addition, we know that force is directly proportional to acceleration. If the smaller force is removed, then the initial force is reduced to
of the initial force. The acceleration of the mass is:


The acceleration of the mass is 2 meters per square second.
This is an excellent question that i do not have the answer to.
