A motorcycle and a bus are moving with the same momentum.Which of them have greater kinetic energy ?
M v = m V
since the motorcycle has less mass, its velocity is greater
K.E. is proportional to the square of the velocity , so the motorcycle will have greater K.E.
thanks for your qestion
when a bus and a motorcycle are moving at the same speed, the motorcycle has more kinetic energy
K.E = P2/2M
Momentum is constant
Then, K.E=1/2M
ie, kinetic energy inversly proportional to mass.
Therefore MOTOR CYCLE have great KINETIC ENERGY
To determine which object has greater kinetic energy, we need to remember that kinetic energy is directly proportional to the square of an object's speed. The formula for kinetic energy (KE) is:
KE = 1/2 * mass * velocity^2
Since both the motorcycle and the bus have the same momentum, we can say that their masses (m) and velocities (v) are inversely proportional. This means that if one object's mass is larger, the other object's velocity must be higher to maintain the same momentum.
Now, let's consider the scenario where the motorcycle has a smaller mass compared to the bus. In order for the momentum to remain constant, the motorcycle would need to have a higher velocity than the bus. Since kinetic energy is proportional to the square of velocity, this means that the motorcycle, with its higher velocity, would have a greater kinetic energy.
On the other hand, if the bus has a smaller mass compared to the motorcycle, the bus would need to have a higher velocity to maintain the same momentum. In this case, the bus would have a greater kinetic energy due to its higher velocity.
Therefore, the motorcycle or the bus can have greater kinetic energy, depending on their masses and velocities. Without specific values for mass or velocity, it is impossible to determine which object has a greater kinetic energy.
