An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? (Formula: ) KE=1/2mv squared
7.5 kg
15 kg
60 kg
120 kg

Answer:15kg

Explanation:

kinetic energy=ke=480J

Velocity=v=8m/s

Mass=m

Ke=0.5 x m x v x v

480=0.5 x m x 8 x 8

480=32m

Divide both sides by 32

480/32=32m/32

15=m

Mass=15kg

Applying the given expression we substituted the given data and got the mass to be  15 kg

Kinetic Energy

Given Data

  • Kinetic Energy KE  = 480 J
  • Velocity v = 8m/s
  • Mass =???

Applying the expression which is KE = 1/2mv^2

Subsituting our given Data into the given expression

480 = 1/2*m*8^2

480 = 1/2*m*64

480 = m*32

Divide both sides by 32

m = 480/32

m = 15 kg
