Question

A car has a mass of 500kg in a moving speed of 10m/s. Find its kinetic energy

Answer 1

Answer:

kinetix energy is 2.5*10^4 J

Explanation:

K.E.=1/2 * mv^2

m=500kg

v=10m/s

k.E.=500*10*10/2

K.E.=50000/2

K.E.=25000J

Answer 2

AnsWer :

Mass of car = 500kg

Speed of car = 10m/s

We have to find kinetic energy of car$.$

⧪ Kinetic energy : Energy which a body possesses by virtue of being in motion.

Formula : K = 1/2 × mv²

• K denotes kinetic energy
• m denotes mass
• v denotes speed

It is a scalar quantity having only magnitude.

SI unit : J

⭆ K = 1/2 × mv²

⭆ K = 1/2 × (500)(10)²

⭆ K = 250 × 100

⭆ K = 25 kJ
