A) 1.3
B) 1.9
C) 2.1
D) 0.9
Correct Answer: A
Solution :
There is only gravitational force is acting on the lift. As power, \[P=Fv\] \[\Rightarrow \] \[P=mgv\] \[=500\times 9.8\times 0.2=980\,W.\] Now, 746 watt = 1 hp So, 980 watt\[=\frac{980}{746}\text{hp}=13\,\text{hp}\]You need to login to perform this action.
