Web4 de mar. de 2024 · Mass of a person, m = 50 kg If the lift is descending with a downward acceleration of To find, The reading of the weighing scale. Solution, Let N is the weight on the weighing scale. The net force acting on the man on the lift that is moving in downward direction is given by : a is acceleration of lift So, the reading of the weighing scale is 50 N. WebFor a mass m= kg, the elevator must support its weight = mg = Newtons to hold it up at rest. If the acceleration is a= m/s² then a net force= Newtons is required to accelerate the mass. This requires a support force of F= Newtons. Note that the support force is equal to the weight only if the acceleration is zero, and that if the acceleration is negative …

Answer: 50 ÷ 1.30 = 38.4625 ÷ 1.10 = 22.727 or 22.7340 ÷ 1.50 = 26.666 or 26.6775 ÷ 1.70 = 44.117 or ... WebThis acts on a weighing machine which offers a reaction R given by the reading of weighing machine. This reaction exerted by the surface of contact on the person is the apparent weight of the person. When lift is accelerating upwards at the rate of a , then reaction. R− mg = ma ∴ R = m(g +a) cyberpunk best scopes
