Explanation:
Given that,
Mass of the block, m = 5 kg
Spring constant, k = 2000 N/m
The block is pulled down 5.0 cm from the equilibrium position and given an initial velocity of 1.0 m/s back towards equilibrium.
(a) The angular frequency is given by :
Since, , f is frequency
(b) The velocity of particle executing SHM is given by :
x is displacement from equilibrium position
(c) The total mechanical energy of the motion in SHM is given by :
Hence, this is the required solution.
Answer:
24 Newtons
Explanation:
The force exerted in the middle cube needs to be enough to move the middle cube and the right cube with an acceleration of 2 m/s2.
The mass of those two cubes combined is 6 + 6 = 12 kg
So, using the following equation, we can find the force:
Force = mass * acceleration
Force = 12 * 2
Force = 24 Newtons
