# Which has more momentum, a #7kg# object moving at #4m/s# or a #8kg# object moving at #5m/s#?

You know momentum is the product of mass and velocity

So you have

To calculate momentum, use the formula: momentum = mass × velocity.

For the first object: momentum = 7 kg × 4 m/s = 28 kg*m/s.

For the second object: momentum = 8 kg × 5 m/s = 40 kg*m/s.

Therefore, the second object (8kg moving at 5m/s) has more momentum with 40 kg*m/s compared to the first object's 28 kg*m/s.

- A ball with a mass of #4 kg # and velocity of #4 m/s# collides with a second ball with a mass of #2 kg# and velocity of #- 1 m/s#. If #15%# of the kinetic energy is lost, what are the final velocities of the balls?
- A ball with a mass of #2 kg # and velocity of #1 m/s# collides with a second ball with a mass of #7 kg# and velocity of #- 4 m/s#. If #40%# of the kinetic energy is lost, what are the final velocities of the balls?
- The velocity of an object with a mass of #2 kg# is given by #v(t)= sin 5 t + cos 6 t #. What is the impulse applied to the object at #t= pi /4 #?
- The kinetic energy of an object remains constant during an elastic collision. Is that true or false?
- A ball with a mass of # 6 kg# is rolling at #7 m/s# and elastically collides with a resting ball with a mass of # 8 kg#. What are the post-collision velocities of the balls?
