$\underline\bold{Physics \:Question}$

Mass of car ,m = 1500kg.
Initial velocity = 30kmh.
${\huge{\mathfrak{30×1000m/:60×60s}}}$

similarly, the final velocity of the car.
v= 60 km h
= 50/3 m s.

Therefore the initial kinetic energy of the car.

E = 1/2m u^2

= 1/2 × 1500kg × { 24/ 3 m s}^2

= 156250 J

Answer 2

Mass of car ,m = 1500kg.
Initial velocity = 30kmh.
30×1000m 60×60s 30×1000m60×60s

similarly, the final velocity of the car.
v= 60 km h
= 50/3 m s.

Therefore the initial kinetic energy of the car.

E = 1/2m u^2

= 1/2 × 1500kg × { 24/ 3 m s}^2

= 156250 J
