Answer:If it was thrown downwards verticly along the plumb line and was unobstructed and assuming no air resistance
Using laws of motion
v=u+at
v= final velocity after t=1 second
u is initial velocity which is 0 (assuming initial rest)
a=g= acceleration due to gravity 9.8 m/s^2
v=20+9.8*1
v=29.8 m/s
