31.64 m/s with velocity fast is it moving 1.8 s after it was thrown vertically downwards at a speed of 14 m/s from the top of a tall building.
V= u + gt= 14 + 9.8×1.8 = 14 + 17.64 = 31.64 m/s
When a body is travelling in a straight line, its estimated "rate of change of displacement in relation to time" is referred to as its velocity.
Speed is a scalar number since it lacks a direction and the value it receives from the distance-to-time ratio simply indicates its magnitude. It doesn't provide any guidance information. Because it always has a direction, velocity is a vector. As a result, when the displacement to time ratio for linear velocity is determined, it provides both the direction and the magnitude.
