Question

calculate the kinetic energy of a car of mass 500 kg moving with a velocity of 18 kilometre per hour find the new kinetic energy if two persons of mass 50 kg of each sit in a car​

Answer 1

This is the answer of the question.please mark it brainiest

Answer 2

Explanation:

K.E = mv^2/ 2

K.E when people are not sitting in it:

Mass m= 500kg

v= 18km/h

K.E = 500 × (18)^2/2

K.E = 81000 N

Now when two people are sitting in car of 50 mass each m= 500+50+50 = 600kg

K.E = 600×(18)^2/2

K.E = 97200 N
