Question

lorry and a car moving with same kinetic energy brought to rest by applying the same retarding force then who is which will be come first at rest

Answer 1

HEY BUDDY..!!

HERE'S THE ANSWER.

________________________________

♠️ Kinetic energy is the energy possessed by the body by virtue of it's motion..

♠️ Regarding force is force which opposes the motion of vehicle .

✔️ Given that same kinetic energy and same retardation force has been applied.


✔️ Work done by brakes = Force × displacement

✔️ KE = 1 / 2 m ( v )^2


▶️ By above statement we can conclude , Car and lorry will come to rest at same time..

HOPE HELPED..

JAI HIND..

Answer 2

Answer:

both car and lorry have equal kinetic energy.

⇒ work done by both is same

⇒ force × displacement in both is same

as retarding force in both is same

⇒displacement due to retarding force in both is also same.
