A small block is connected to one end of a massless spring of un - stretched length 4.9 m . The other end of the spring (see the figure) is fixed. The system lies on a horizontal frictionless surface. The block is stretched by 0.2 m and released from rest at t = 0 . It then executes simple harmonic motion with angular frequency (omega) = (pi//3) rad//s . Simultaneously at t = 0 , a small pebble is projected with speed (v) from point (P) at an angle of 45^@ as shown in the figure. Point (P) is at a horizontal distance of 10 m from O . If the pebble hits the block at t = 1 s , the value of (v) is (take g = 10 m//s^2) . .

A small block is connected to one end of a massless spring of un-stretched length 4.9 m. The other end of the spring (see the figure) is fixed. The system lies on a horizontal frictionless surface. The block is stretched by 0.2 m and released from rest at t = 0. It then executes simple harmonic motion with angular frequency omega = (pi)/(3) rad/s . Simultaneously at t = 0, a small pebble is projected with speed nu from point P at an angle of 45^(@) as shown in the figure. Point P is at a horizontal distance of 10 m from O. If the pebble hits the block at t = 1s, the value of nu is (take g = 10 m/ s^(2) )
