Question

the mass of body in 40 gram and velocity 10 cm per second the mass and velocity of another body 80g
and 15 cm per second compare their kinetic energy​

Answer 1

Answer:

1:3

Explanation:

KE = ½MV²

M1 = 40g

V1 = 10 cm/s²

KE1 = ½ × 40 × 10 = 200

M2 = 80g

V2 = 15 cm/s²

KE 2 = ½ × 80 × 15 = 600

KE1 : KE2 = 200:600 =

1:3
