Question

Elevator is required to lift a body of mass 65 kg. find the acceleration of the elevator which could cause a reaction of 800 Newton on the floor

Answer 1

the acceleration is 12.30 m per sec

since,
(F )Force =mass(M) x acceleration (A)
therefore on rearranging
A=F/A
A=800/65
A=12.30

Answer 2

Given that

Mass = 65kg

Force = 800N

we know that

F = ma

So putting value

800 = 65 × acceleration

Acceleration = 800/65

Acceleration = 12.30
