Respuesta :
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=[tex]\sqrt{(ke/(0.5*m)[/tex]
v= 3.6/(0.5×0.65)
=[tex]\sqrt (11077/10)/10[/tex]
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.
Answer:
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
[tex]v=\sqrt{\frac{2*E}{m} }[/tex]
[tex]v = \sqrt{\frac{2*3.6}{0.65} }=\sqrt{11.08}[/tex]
So combined velocity is 3.33 m/s.
