Answer: 13.0m/s
Explanation:
26sin(30)=v in y-direction or vertical direction
v=26m/s*sin(30)=26m/s*(1/2)=13.0m/s
Answer:
The stiffness of one of the individual spring is 390 N/m.
Explanation:
It is given that 43 identical springs are placed side-by-side and connected to a large massive block.
The stiffness of the 43 spring combination is 16770 N/m
We need to find the stiffness of one of the individual springs. Let k is the stiffness of one spring. The effective spring stiffness of this width spring is given by :



k = 390 N/m
So, the stiffness of one of the individual spring is 390 N/m. Hence, this is the required solution.
