Apick-up truck with two passengers weighs about 14100 n. in good driving conditions around a curve, the maximum friction with the road is equal to the truck's weight. what is the minimum safe curve radius that the truck could negotiate at 26.2 m/s?

r=68.64 m

Step-by-step explanation:

Given that

Weight ,wt= 14100 N

mass m = 1410 kg             ( g = 10 m/s²)

Friction force = Weight

Fr= 14100 N

v= 26.2 m/s

Lets take radius of the curve =  r

To balance the truck ,radial force should be equal to the friction force

mv² = Fr x r

1410 x 26.2² = 14100 x r

r=68.64 m

Therefore radius of the curve will be 68.64 m

Answer - r=68.64 m

step-by-step explanation:

the areas of two similar triangles are 18 cm2 and 8 cm2. one of the sides of the first triangle is 4.5 cm. what is the length of the corresponding side of the other triangle?

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
