A 14000N car traveling at 25m/s rounds a curve of radius 200m. Find the following: a. The centripetal acceleration of the car.
tamaranim1 [39]

Answer:

Explanation:

Given

Weight of car W=14,000\ N

mass of car m=\frac{14,000}{9.8}=1428.57\ N

velocity of car v=25\ m/s

radius r=200\ m

(a)Centripetal acceleration is given by

a_c=\frac{v^2}{r}

a_c=\frac{25^2}{200}

a_c=3.125\ m

(b)Force that provide centripetal acceleration

F=F_c=\frac{mv^2}{r}

F=\frac{1428.57\times 25^2}{200}

F=4464.285\ N

(c)Friction force between car and tires is given by

=\mu N

where \mu=coefficient of static friction

N=normal reaction

Centripetal force will balance the friction force

F_c=F_r

4464.285=\mu \times 1428.57\times 9.8

\mu =0.318

in mammal the weight of the heart approximately 0.5% total body weight write linear model that gives the heart weight in terms o
maks197457 [2]

Let the total weight of the body be = x

Let the weight of the heart of the mammals be = y

Now the given percentage of 0.5 %, we will convert it into decimal form,

so this is equal to 0.005 in decimal form,


so the linear equation that gives the heart weight in terms of body weight will be,

y = 0.005x
