Momentum = Mass x Velocity = 11 x 10 = 110 Ns (Newton seconds)

∙ 11y agop = m•v = momentum, where m is mass in kg and v is velocity in m/s.
p = 1kg x 10m/s = 10kg•m/s

What is the kinetic energy of a 10kg bicycle moving at 10 ms?

Can objects with different masses have the same momentum?
Yes. Momentum is rigidly defined as the product of mass and velocity. Velocity describes both a speed and a direction. So let's take two metal balls. One weighs 10 kilograms (kg) and the other weighs 20kg. We roll the 10kg ball along a flat and level floor at 2 meters per second (m/s) and the 20 kg ball at 1 m/s. 10*2 = 20*1 so they have the same momentum. If you have a friend roll the balls for you to catch some distance away, making sure after a few tests to roll the lighter ball at twice the speed of the heavier ball, you will find that it "feels" as if both balls hit your hand with about the same force. Your hand is stopping each ball. That is a force which is defined as the rate of change in momentum. Stopping each ball will cause your muscles to exert about the same strength to stop each ball, even though one is moving at double the speed of the other. You will then feel that two objects can indeed travel at different speeds and yet have the same momentum. JGS
Which would have greater effect on kinetic energy of an object - doubling the mass or doubling the velocity?
Doubling mass affects kinetic energy in that the greater the mass, the greater the kinetic energy. OK, but if you have a 10kg mass traveling at 2m/s and it bumps into and sticks to a 10g mass, the resultant speed would be 1m/s. The momentum stays the same. KE before is 10*2*2/2= 20, while the KE after is 20*1*1/2= 10. So it is not that the above answer is wrong, but rather, you question is not clear.

Which weighs more 10kg stack of books or 10kg piece of Styrofoam?
Both the 10kg stack of books and the 10kg piece of Styrofoam weigh the same amount, 10kg, because weight is a measure of the force due to gravity acting on an object's mass.
Where does kinetic energy go after it is used?
If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.
