a =  \frac{f2}{f1}
\frac{20}{100 }  = 0.200
a=advantage of the machine
f1=force that is applied
f2=force the machine applied

A 46.0-kg box is being pushed a distance of 8.80 m across the floor by a force P whose magnitude is 171 N. The force P is parall
dolphi86 [110]

Answer:

a) 1504.8 J

b) 991.76 J

c) 0J

d) 0J

Explanation:

(a) The work done by the force P on the box is given by the following formula:

W_P=Px

P: applied force = 171N

x: distance in which the for P is applied = 8.80m

you replace the values of P and x and obtain:

W_P=(171N)(8.80m)=1504.8J

(b) The work don by the friction force is:

W_f=F_fx=\mu N x=\mu Mg x

μ = coefficient of kinetic friction = 0.250

M: mass of the box = 46.0kg

g: gravitational constant = 9.8 m/s^2

W_f=(0.250)(46.0kg)(9.8m/s^2)(8.80m)=991.76J

(c) The Normal force is

N=Mg=(46.0kg)(9,8m/s^2)=450.8N

but this force does not do work on the box because the direction is perpendicular to the direction of the force P.

W_N=0J

(d) the same as before:

W_g=0J

A race car starts from rest on a circular track of radius 378 m. The car's speed increases at the constant rate of 0.580 m/s2. A
insens350 [35]

Answer:

a) V=14.904m/s

b) d = 191.49 m

c) t= 25.696 s

Explanation:

From the question we are told that:

Radius r =378m

Acceleration a=0.580

a)

Generally the  equation for speed of the car is mathematically given by

 a=\frac{v^2}{r}

 V=\sqrt{a*r}

 V=\sqrt{0.58*383}

 V=14.904m/s

b)

Generally the  equation for distance traveled of the car is mathematically given by

 V^2=u^2+2ad

 d=\frac{V^2}{2a}

 d=\frac{14.904^2}{2*0.58}  

 d = 191.49 m

c)

Generally the  equation for time of the car is mathematically given by

 V=u+at

 t=\frac{V}{a}

 t=\frac{14.904}{0.58}

 t= 25.696 s
