An object has a velocity of 8 m/s and a kinetic energy of 480 j. what is the mass of the object? (formula: )

Mass of an object is 15 kg.

Explanation:

It is given that,

velocity of an object, v = 8 m/s

Kinetic energy of an object, KE = 480 J

Kinetic energy of an object is due to the motion of an object. The mathematical relationship is given by :

Where m is the mass of an object

m = 15 kg

Hence, the mass of an object is 15 kg

not moving. pos accel,

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
