A centripetal force of 1,400 newtons acts on a car rounding a curve with a radius of 150 meters. If the car has a mass of 2,100
kilograms, find its velocity, in meters per second.
1 answer:
In circular motion, the centripetal force is v²/R , and the
centripetal force is (mass) x (acceleration) = M v²/R .
1400 = 2100 v² / 150
Divide each side by 2100 : 2/3 = v² / 150
Multiply each side by 150 : 100 = v²
Square root each side: v = 10 m/s .

We know, Speed = Wavelength * Frequency
Speed = 32.4 * 3
Speed = 97.2 m/s
So, option D is your correct answer.
Hope it helped.
Kinetic energy is energy in motion and potential energy is stored energy
B. In step 3
They incorrectly solved for x. It should have been x=-3 and x=5
Internal energy or thermal energy.
