Question

A person weighing 25 kg stands in an elevator. The elevator accelerated

upward with a constant value of 7 m/s2. Assume gravitational acceleration

as 9.81 m/s2. If the elevator cage weights 2000 N, the tension of cable which

supports the elevator is​

Answer 1

Explanation:

there is a net force upwards since it is being accelerated upwards

#so

Fnet=ma

if T=tension in the cable

the net force is T−16917

the mass will be 169179.8

∴T−16917=169179.8×2.5

∴T−16917=4315.56

T=4315.56+16917

T=21232.56N

Answer 2

Answer:

1. T= 225*g+225*7=3782.25
