A 1000 kg car is traveling at 20 m/s. How much kinetic energy does it

Here, Given- mass=1000kg Speed=20m/s Formula for Ek=1/2mv² Putting the value in the formula We get Ek=1/2×1000×20 =10000joules.

Use the formula 1/2 m v^2 to get 1/2 x 1500 x 20 x 20 = 200 x 1500 = 300,000 Joules or 300 kJ.

The kinetic energy is given by the formula

K.E = \frac{1}{2} m v^{2}

Plug in the value of mass m = 1500 and v=25 in this to get

K.E = \frac{1}{2} \times 1500 \times 25 \times 25

= 468,750 J

1 KJ = 1000 J

So, dividing the above value by 1000 , we get

= 468.750 KJ

Use the K.E formula \frac{1}{2}mv^{2} and plug in the respective given values to find these - 1. \frac{1}{2}\cdot 1500\hspace{1mm} kg \cdot 4\Big(\frac{m}{s}\Big)^{2}= 30,000 J A 1500 kg car moving at 2 m/s will have a kinetic energy of 30,000 J. 2.\frac{1}{2}\cdot 1500 kg\hspace{1mm} \cdot 400 \Big(\frac{m}{s}\Big)^{2} = 300,000 J A 1500 kg car moving at 20 m/s will have a kinetic energy of 300,000 J. 3. \frac{1}{2}\cdot 200 \hspace{1mm}kg \cdot 4 \Big(\frac{m}{s}\Big)^{2} = 400 J A 200 kg elephant moving at 2 m/s will have a kinetic energy of 400 J. 4. \frac{1}{2}\cdot 2 \hspace{1mm}kg \cdot 4 \Big(\frac{m}{s}\Big)^{2} = 4J A 2 kg puppy moving at 2 m/s will have a kinetic energy of 4J. Remember the conversion, that 1 J = 1 kg \cdot \frac{m^{2}}{s^{2}}
