Ashley squirrel, named Jackie, rides on a bicycle with a constant kinetic energy of 3.6J. The mass of combination of Jackie and the bicycle is 0.65 kg. What is the velocity of the combination of Jackie and the bicycle?

The velocity of the combination of Jackie and the bicycle is 3.328 m/s.

Explanation:

From the given data the constant kinetic energy is 3.6 J. The mass of combination is 0.65 kg. To find the velocity of the combination of Jackie and the bicycle the formula  is

KE = 0.5 x mv2.

To find velocity,

V2=ke/(0.5×m)

V=

v= 3.6/(0.5×0.65)

=

v= 3.328 m/s

Hence, the velocity of the combination of Jackie and the bicycle is 3.328m/s.

The combined velocity is 3.33 m/s.

Explanation:

Kinetic energy is the measure of the energy experienced by moving objects. So the mathematical expression of kinetic energy will be directly proportional to the product of mass and square of the velocity of the object.

As the combined mass of Jackie and bicycle is 0.65 kg and the kinetic energy  is given as 3.6 J. Then the velocity of the combined Jackie and bicycle is

Kinetic energy = 1/2 mv²

So combined velocity is 3.33 m/s.

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

so easy. just google the electromagnetic waves and it’ll pop up.
