which has greater cenetic energy a car traveling 30.0 km/hr or one twice as heavy traveling at 15 km/hr?

iVinArrow [24]

Answer:

30 km/h car

Step-by-step explanation:

From analysis the car traveling at 30 km/h has greater kinetic energy

we can deduce it from the expression of kinetic energy which is

$KE=\frac{1}{2} mv^2$

Assuming the mass m= 1 kg

For the 30 km/h

$KE=\frac{1}{2}*1*30^2 \\\\KE=\frac{1}{2}*1*900\\\\\KE=450 J$

For the 15 km/h

$KE=\frac{1}{2}*2*15^2 \\\\ KE=\frac{1}{2}*2*225 \\\\\ KE=\frac{1}{2}*450 J\\\\\ KE=225 J$

Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE

Triangle ABC is an obtuse triangle with the obtuse angle at vertex B. Angle A must be

wlad13 [49]

We have to find the correct statement for angle A in a triangle ABC, which is an obtuse triangle. We know that angle B is obtuse ( greater than 90 degrees ). Therefore angles A and C must be less than 90 degrees. Angle A can not be congruent to angle B ( angle B > angle A ). It can be congruent to angle C but just in case that ABC is an isosceles obtuse triangle. Answer: Angle A must be A ) less than 90 degrees.
