Question

A man of mass m is 60 kg is standing on weighing machine fixed on a triangular wedge of angle 60 degrees.The wedge is moving with an upward acceleration a=2m per second square the weight registered by machine is

Answer 1

Thus the weight registered by machine is W = 360 N

Explanation:

We are given that:

Mass of man = 60 Kg

Angle "θ" = 60°

macosθ + mgcosθ = N

N = 60 x 2 x 1/ 2 + 60 x 10 x 1/2

N = 60 + 60 x 5

N = 60 + 300

N = 360 N

Thus the weight registered by machine is W = 360 N

Answer 2

Thus the weight registered by machine is W = 360 N

Explanation:

We are given that:

Mass of man = 60 Kg

Angle "θ" = 60°

macosθ + mgcosθ = N

N = 60 x 2 x 1/ 2 + 60 x 10 x 1/2

N = 60 + 60 x 5

N = 60 + 300

N = 360 N

Thus the weight registered by machine is W = 360 N
