A woman pushes a lawn mower with a constant force of 112 Newtons at an angle of 37◦ with respect to the horizontal. The lawn mow

user100 [1]

Answer:

1.0.024 hp

Step-by-step explanation:

We are given that

Constant force=F=112 N

$\theta=37^{\circ}$

Speed of lawn mower,v=20 cm/s= $20\times 10^{-2} m/s$

1 m=100 cm

1 hp=746 watt

We have to find the power output

Force applied by women on lawn mower= $Fcos\theta=112cos 37^{\circ}$

Force applied by women on lawn mower= $89.45$ N

Power output,P= $Fv$

Using the formula

Power output= $89.45\times 20\times 10^{-2}=17.89 watt$

Power output,P= $\frac{17.89}{746}=0.024$ hp

Hence, option 1 is true

DedPeter [7]

Answer:

y = 2x + 3

Step-by-step explanation:

the same slope would be 2x still

the 3rd and 4th choice are the only ones that have the correct slope

and 1 unit lower than 4 is 3
