A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscillation. The speed of the bob at its mean position is 1 ms-1. What is the trajectory of the bob if the string is cut when the bob isat its mean position?

The bob has a horizontal velocity in its mean position. The bob will act like a projectile if the string is severed, and it will fall to the earth after travelling a parabolic route.
