One end of a massless spring is attached to a wall & another end is attached to a block of mass m = 20 g (as shown in Fig. 2). When the block is stretched horizontally to a distance 5 cm from its rest position, the force acting on the block is 10 N. (a) Calculate the spring constant. (b) Now consider one end of the same spring system is attached to the ceiling. Take the hanging end point of the spring as reference to the gravitational
One end of a massless spring is attached to a wall &
another end is attached to a block of mass m = 20 g (as
shown in Fig. 2). When the block is stretched horizontally
to a distance 5 cm from its rest position, the force acting
on the block is 10 N.
(a) Calculate the spring constant.
(b) Now consider one end of the same spring system is attached to the ceiling. Take
the hanging end point of the spring as reference to the gravitational potential. When the block
is attached to the hanging end point of the spring, it extends a distance d. Calculate the value
of d. Also calculate the block’s total potential energy at this position.
(c) Calculate the time period & angular frequency for both the vertical and the
horizontal oscillations.
