A block of mass m is attached to a massless spring of force constant k, the other end of which is fixed from the wall of a truck as shown in the figure. The block is placed over a smooth surface and initially the spring is unstretched. Suddenly the truj starts moving towards right with a constant acceleration `a_(0)`. If the block is observed from the truck

Options

A. the block will execute SHM
B. the time period of oscillations of block will be `2pi sqrt((m)/(k))`
C. the amplitude of oscillation of block will be `(ma_(0))/(k)`
D. the energy of oscillations of block will be `(m^(2) a_(0)^(2))/(k)`

Answer

A, B, C
