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
Assuming the mass m= 1 kg
For the 30 km/h
For the 15 km/h
Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE
X is the smaller number. 3x + 15 is the larger number. So x + 3x + 15 = 63. 4x + 15 = 63.
4x = 48. x = 12. (Smaller number) The larger 36 + 15 or 51.
