A spring suspended vertically is 11.9 cm long. When you suspend a 37 g weight from the spring, at rest, the spring is 21.5 cm lo
ng. Next you pull down on the weight so the spring is 25.2 cm long and you release the weight from rest. What is the period of oscillation?
1 answer:
Answer:
Time period of oscillations is 0.62 s
Explanation:
Due to suspension of weight the change in the length of the spring is given as


now we know that spring is stretched due to its weight so at equilibrium the force due to weight is counter balanced by the spring force



Now the period of oscillation of spring is given as

Now plug in all values in it

Answer:
F = 2389.603 N
Explanation:
Given:
Mass m = 1,369.4 kg
Initial velocity u = 28.9 m/s
Final velocity v = 20 m/s
Time t = 5.1 s
Find:
Net force
Computation:
a = (v - u)/t
a = (20 - 28.9)/5.1
a = -1.745 m/s²
F = ma
F = (1369.4)(1.745)
F = 2389.603 N
Explanation:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction
Answer:
the force exerted by the seat on the pilot is 10766.7 N
Explanation:
The computation of the force exerted by the seat on the pilot is as follows:

Hence, the force exerted by the seat on the pilot is 10766.7 N
Force. Force is measured by newtons, probably because he came up with the equations to calculate force.
