Question

Calculate the kinetic energy of a 1000 kg car traveling at 16.67 m/s.

Answer 1

Explanation:

As we know K.E = 1/2 MV^2

Mass = 1000 kg

Velocity = 60km/h = 50/3 m/s

K.E = 1/2×1000×2500/9= 1.388×10^5J

Answer 2

Answer:

138944.45J

Explanation:

We know that kinetic energy is defined mathematically as

               $K.E=1/2mv^2$

we are given with:

mass(m)=1000kg

velocity(v)=16.67m/s

by substituting the values of mas and velocity we get

1/2×1000×16.67×16.67

=138944.45$j$

*Therefore the kinetic energy of a car is 138944.45joule.
