An elevator of mass 4800kg is supported by a cable which can safely withstand a maximum tension of 60 000N. The maximum upward acceleration the elevator can have is
-
2.5ms-2
- 5.0ms-2
- 7.5ms-2
- 10.0ms-2
The correct answer is: A
Explanation
a = \(\frac{F}{m}\)= \(\frac{60000 -(4800 \times10)}{4800}\)
= 2.5ms-2
