A 60.0-kg person rides in elevator while standing on a scale. The elevator is traveling downward but

slowing down at a rate of 2.00 m/s2. The reading on the scale is closest to

Respuesta :

The effective acceleration will be 9.8 + 2 = 11.8 m/s^2
The reading on the scale will be 60x11.8 = 708 N

The reading on the scale is closest to 708N.

What is weight?

The weight of any object is the mass times the acceleration due to gravity on Earth or any other planet.

Weight W = mg

where g = 9.81 m/s²

Given is the mass of person, m = 60kg, and the acceleration downward of the elevator a =2 m/s² , then the weight will be

W = m(a+g)

W = 60x (2+9.81)

W=  60x11.8

W= 708 N

Thus, reading on the scale will be 708N
