Simple Harmonic Motion

Physics
1 answer:
Delvig [45]3 years ago

- The net force is greatest at the position of maximum displacement

- The net force is zero when at the equilibrium position

Explanation:

The motion of a spring is a Simple Harmonic Motion, in which the displacement of the end of the spring is given by a periodic function of the form

x=Asin (\omega t)

where A is the amplitude (the maximum displacement), and \omega the angular frequency of the motion.

We can analyze the net force acting on the spring by looking at Hooke's law:

F=kx

where

F is the net force

k is the spring constant

x is the displacement

From the equation, we notice immediately that:

  • The net force is the greatest when the displacement x is the greates, so at the position in which the spring has maximum compression or stretching
  • The net force is zero when the displacement x is zero, so when the spring crosses the equilibrium position

Question 1 (1 point)
TiliK225 [7]

Answer:

The resultant velocity of the plane relative to the ground is;

150 kh/h north

Explanation:

The flight speed of the plane = 210 km/h

The direction of flight of the plane = North

The speed at which the wind is blowing = 60 km/h

The direction of the wind = South

Therefore, representing the speed of the plane and the wind in vector format, we have;

The velocity vector of the plane = 210.\hat j

The velocity vector of the wind = -60.\hat j

Where, North is taken as the positive y or \hat j direction

The resultant velocity vector is found by summation of the two vectors as follows;

Resultant velocity vector = The velocity vector of the plane + The velocity vector of the wind

Resultant velocity vector = 210.\hat j  + (-60.\hat j) =  210.\hat j  - 60.\hat j = 150.\hat j

The resultant velocity vector = 150.\hat j

Therefore, the resultant velocity of the plane relative to the ground = 150 kh/h north.

Two objects are dropped from different heights at the same instant. If the first object takes 10.7 seconds to hit the ground and
Lubov Fominskaja [6]

Answer:

The answer to your question is : 521.8 m

Explanation:

Data:

Different heights

Time first object (tfo) = 10.7 s

Time second object (tso)= 14.8 s

Initial speed of both objects(vo) = 0 m/s

a = 9.81 m/s²

Formula:

h = vot + 1/2 (a)(t)² but vo = 0    so, h = 1/2 (a)(t)²

Then, height fo      h = 1/2 (9.81)(10.7)² = 561.6 m

          height so     h = 1/2(9,81)(14.8)² = 1074.4 m

Difference in their heights =  1074.4 m - 561.6 m = 521.8 m
