Hello!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object ?

We have the following data: 

KE (Kinetic Energy) = 480 J

m (mass) = ? (in Kg)

v (speed) = 8 m/s

Formula to calculate kinetic energy:

Solving:

b) 15 kg

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
