Did you know?
WebMar 28, 2015 · An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object. WebGood evening, I'm trying to calculate what kind of impact force a falling object would have once it hit something. This is my attempt so far: Because x = 1 2 a t 2, t = 2 x / a v = a t, therefore v = a 2 x / a E k = 1 2 m v 2, so E k = 1 2 m ( 2 a x) = m ⋅ a ⋅ x Since W = E k = F i s, F i = E k / s = ( m ⋅ a ⋅ x) / s
