Expert's answer

An empty 210 kg elevator accelerates upward

at 1.8 m/s2.

The acceleration of gravity is 9.8 m/s2 .

What is the tension in the cable that lifts

the elevator cab?

Answer in units of N

According to the second Newton's law the tension in the cable that lifts the elevator cab is

T = M*g + M*a = M*(g+a) = 210[kg]*(9.8[m/s²] + 1.8[m/s²]) = 2436[N].

at 1.8 m/s2.

The acceleration of gravity is 9.8 m/s2 .

What is the tension in the cable that lifts

the elevator cab?

Answer in units of N

According to the second Newton's law the tension in the cable that lifts the elevator cab is

T = M*g + M*a = M*(g+a) = 210[kg]*(9.8[m/s²] + 1.8[m/s²]) = 2436[N].
