How much force is required to accelerate a 10kg bicycle along with it's 10kg?
To accelerate a 20kg bicycle (10kg bike + 10kg rider) at a rate of 2 m/s^2, you would need a force of 40 newtons. This is calculated by multiplying the mass (20kg) by the acceleration (2 m/s^2).
A 10kg cart is moving at 5ms collides with a 5kg cart at rest and Causes it move 10ms What principle explain the result?
The principle of conservation of momentum explains this result. The total momentum of the system before the collision is equal to the total momentum after the collision. In this case, the momentum gained by the 5kg cart moving at 10 m/s is equal to the momentum lost by the 10kg cart, resulting in a balanced conservation of momentum.
How much momentum will a dumbbell of mass 10 kg transfer to the floor if it falls from a height of 80 cm Take its downward acceleration to be 10ms-1?
First, calculate the velocity of the dumbbell just before hitting the floor using the equation v^2 = u^2 + 2as, where u is the initial velocity (0 m/s), a is the acceleration (10 m/s^2), and s is the distance (0.8 m). The velocity obtained will be 4 m/s. Now, calculate the momentum by multiplying the mass of the dumbbell (10 kg) by the final velocity (4 m/s) to get a momentum of 40 kg m/s. The dumbbell will transfer this momentum to the floor upon impact.
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.
