Answer» Hey there!! Here is your answer ↓↓ In ORDER to find the mass, when kinetic ENERGY , VELOCITY is GIVEN, we use this formula : Kinetic Energy = ( 1 ÷ 2 ) ( m ) ( v² ) m = mass v = velocity ( 8 m/s ) Kinetic energy = 480 J 480 = ( 1 ÷ 2 ) ( m ) ( 8² ) 480 = ( 1 ÷ 2 ) ( m ) ( 64 ) 480 = 32m m = 480 ÷ 32 m = 15 The mass is 15 kg Hope my answer helps! #BeBrainly @sid071 |
