Answer:

Acceleration will be equal to 3689.16m/sec^2

Explanation:

We have given initial height h = 1 m

Time instant t = 1.2 m-sec = 0.0012 sec

Initial velocity u = 0 m/sec

From third equation of motion we know that v^2=u^2+2gh

So v^2=0^2+2\times 9.8\times 1

v = 4.427 m/sec

We have to find the acceleration

Acceleration is time rate of change of velocity

So acceleration a=\frac{v}{\Delta t}=\frac{4.427}{0.0012}=3689.16m/sec^2

So acceleration will be equal to 3689.16m/sec^2

An elevator filled with passengers has a mass of 1683 kg. (a) The elevator accelerates upward from rest at a rate of 1.20 m/s2 f
artcher [175]

Answer:

the tension is 18513N

Explanation:

Given that

mass = 1683kg

acceleration = 1.2m/s^2

acceleration due to gravity = 9.8m/s^2

T-mg =   ma

T = ma + mg

T = m(a +g)

T = 1683 kg(1.20 m/s2 + 9.8)

T = 1683 (11)

T = 18513N

therefore, the tension is 18513N
