Question

The velocity of a toy car of mass 3kgis 4m/s,the kinetic energy is___

1 point

12 kg m/s

24 kg m/s

48 kg m/s

72 kgm/s

​

Answer 1

Step-by-step explanation:

kinetic energy formula is f*s

Answer 2

Step-by-step explanation:

kinetic energy (KE) is KE = 1/2 x mv^2

the mass of the car (m)=3kg

the velocity of the car (v)=4m/s

The Kinetic Energy(KE)=(1/2)×3×(4)^2

=>(1×3×16)/2

=>48/2=32kgm/s

therefore ,the kinetic energy of the car is 24kgm/s
