Question
A block with mass m = 4.4 kg is attached to two springs with spring constants kleft = 35 N/m and kright = 49 N/m. The block is pulled a distance x = 0.24 m to the left of its equilibrium position and released from rest. (Note:Two springs = one spring of spring constant k1 + k2
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? (Get what they're asking? It's as if the block is connected to a single spring, with a spring constant equal to ??? Use your result from question (1)).
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 0.88 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 0.88 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?
