A stone of mass 0.55 kilograms is released and falls to the ground. Measurements show that the stone has a kinetic energy of 9.8 joules at the point of impact with the ground. What is the stone's velocity when it hits the ground? A)6.3 METERS/SECOND (B)7.2 meters/second (C)8.1 meters/second (D)9.3 METERS/SECOND
@souvik Puoi aiutarmi CAN YOU HELP ME
Puoi aiutarmi= CAN YOU HELP ME? in Italy
wow...btw when the stone is about to hit the ground its all potential energy is converted into kinetic energy... so \[1/2mv ^{2}=9.8\] you know the mass...find v
i got it thank you @souvik
