Question

A mass of truck is 4 times the mass of a car . If both are running at the same speed, calculatr the kinetic energy of the truck with the respect to that of the car
​

Answer 1

Answer:

Explanation:

let velocity of car and truck be v.

mass of car be m1

mass of truck be m2

A/q

m2= 15 m1 _____________equ1

we know

kinetic energy, K = 1/2 mv^2

now,

k1 that is kinetic energy of car

= 1/2m1v^2

and k2 that is kinetic energy of truck

= 1/2m2v^2

so

from equation 1 we can write

\k2 = 1/2×15m1v^2

so

k1/k2=1/2m1v^2÷1/2×$m1v^2

k1/k2=1/4.
