Step-by-step explanation:
20 doesnt fit any of these answers
In plain and short, the whole class is 100%, so we first split it by the ratios, namely by 3+2, so 100/(3+2) and then give 3 pieces to the girls and 2 pieces to the boys, let's do so,
energy is always transformed from one form to another
energy is not created nor destroyed
so when a car starts moving the chemical potential energy of the car is converted to kinetic energy
kinetic energy is the energy that moving objects possess
kinetic energy formula is as follows
Kinetic energy = 1/2 mv²
where m - mass
v - velocity
substituting these values
K.E = 1/2 x 1350 kg x (12 m/s)²
= 1/2 x 1350 x 144 = 97200 J
the kinetic energy of the car is 97.2 kJ
