Answer:
3.38
Step-by-step explanation:
x + y + z = 16.9
x = 2y
y = z

2y (x) + y(y) + y(z) = 16.0
5y = 16.9
y = 3.38
Answer:
1.0.024 hp
Step-by-step explanation:
We are given that
Constant force=F=112 N
Speed of lawn mower,v=20 cm/s=
1 m=100 cm
1 hp=746 watt
We have to find the power output
Force applied by women on lawn mower=
Force applied by women on lawn mower=N
Power output,P=
Using the formula
Power output=
Power output,P=hp
Hence, option 1 is true
