Question

this is based on physics.hey some1 plss answer
A heavy stone hanging from a massless string of length 15 m is projected horizontally with speed 147 m/s. The speed of the particle at the point where the tension in the string equals the weight of the particle is

Answer 1

147 m/s

Answer 2

tension of the string will be equal to the stone's weight when the stone is in equilibrium position. in equilibrium position, in this case, the speed of the stone will be equal to the initial speed

Answer 3

it is equal when it is in horizontal position.
