Ablock with mass m = 7.4 kg is attached to two springs with spring constants kleft = 31 n/m and kright = 53 n/m. the block is pulled a distance x = 0.27 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)?
n
2)what is the effective spring constant of the two springs?
n/m
3)what is the period of oscillation of the block?
s
4)how long does it take the block to return to equilibrium for the first time?
s
5)what is the speed of the block as it passes through the equilibrium position?
m/s
6)what is the magnitude of the acceleration of the block as it passes through equilibrium?
m/s2
7)where is the block located, relative to equilibrium, at a time 1.06 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the block is right of equilibrium give the answer as a positive value)
m
8)what is the net force on the block at this time 1.06 s? (a negative force is to the left; a positive force is to the right)
n
9)what is the total energy stored in the system?
j
10)if the block had been given an initial push, how would the period of oscillation change?
the period would increase
the period would decrease
the period would not change
