Question

A block with mass m = 4.3 kg is attached to two springs with spring constants kleft = 34 N/m and kright = 57 N/m. The b... ... The block is pulled a distance x = 0.22 m to the left of its equilibrium position and released from rest. 1). What is the magnitude of the net force on the block (the moment it is released)?

Answer 1

20.02 N

Step-by-step explanation:

The force the spring exerts is given by a law called Hooke's law

`F=kx`

where

k = Spring constant

x = Displacement

`k_l` = 34 N/m

`k_r` = 57 N/m

Here the block is pulled 0.22 to the left so it will also move 0.22 m to the right

So, the total force is given by

`F=k_lx+k_rx\\\Rightarrow F=34* 0.22+57* 0.22\\\Rightarrow F=20.02\ N`

The magnitude of the net force on the block is 20.02 N
