A weightlifter drops a 15.0-kg barbell from a height of 2.0 m. Calculate the kinetic energy of the barbell as it hits the floor.\ |
|
Answer» SOLUTION: Mass of BARBELL,m= 15kg height, h= 2m potential energy at that point= kinetic energy potential energy= MGH => 15*10*2 (acceleration due to GRAVITY= 10 m/s^2) = 300 joule so,kinetic energy will be 300 joule. _________________ hope it helps☺☺ |
