With mass 2500 kg, the elevator has weight
(2500 kg) <em>g</em> = (2500 kg) (9.80 m/s²) = 24,500 N
The net force on the elevator is 30,000 N - 24,500 N = 5500 N (because its weight pulls it downward, while the tension pulls upward).
The acceleration <em>a</em> of the elevator is obtained from Newton's second law,
(2500 kg) <em>a</em> = 5500 N
<em>a</em> = (5500 N) / (2500 kg)
<em>a</em> = 2.2 m/s²
3/5•(4e+5kg)
:
Factor out 3/5 from the expression
3/5•(4e+5k)
Use the commutative property to reorder the terms
3/5(4e+5k)
