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
Answer:
23.5
Step-by-step explanation:
First the shaded area is 28 but there is a triangle so we have to solve the area of the triangle. (formula for triangle: B x H x 1/2) 3 times 3=9 divided by 2=4.5
28-4.5=23.5
Answer: u are right its c
Step-by-step explanation:
Step-by-step explanation:
We need to factorise 3x
2
−12xy
Here we can take 3x common.
Thus we have 3x
2
−12xy=3x(x−4y)
Hence, factors are 3x,(x−4y).
