Answer:

[tex]sln \\ given \\ velocity \:(v) = 45ms {}^{ - } \\ mass \: of \: car \: (m) = 1120kg \\ kinetic \: enegy(k.e) = x \\ \\ k.e = \frac{1}{2} MV {}^{2} \\ k.e = \frac{1}{2} \times 1120 \times 45 \\ k.e = 25200j[/tex]

the car has kenotic energy is 2500J

The car will , have the kinetic energy of 1134 kJ. The kinetic energy is found as the product of half of mass and the square of  velocity.

What is kinetic energy?

The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.

The given data in the problem is;

A car traveling with a velocity,v= 45 m/s

The mass is, m= 1120 kg.

The kinetic energy is found as;

[tex]\rm KE = \frac{1}{2} mv^2 \\\\\ \rm KE = \frac{1}{2} 1120 (45)^2 \\\\\ \rm KE = 1134 \ kJ[/tex]

Hence, the car will , have the kinetic energy of 1134 kJ.
