electric charge and time
none of these
An object having a pi of 30kg m/s has ended with a pf of 40 kg m/s. What impulse caused this?
2kg m/s
10kg m/s
70kg m/s
5kg m/s
If the change of momentum of an object is 50kg m/s, we can say the impulse is equal to:
0 kg m/s
25 kg m/s
50 kg m/s
100 kg m/s

10N
4N
5N
50N
An object has Pi of 20 kgm/s ends with a Pf of 40 kgm/s. How long would a 5N force need to act?

An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of impulse.
1st egg experienced more impulse
2nd egg experienced more impulse
both experienced the same impulse
An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of force and time, the second egg must have experienced...
more force, but less time
less force, but more time
more force, and more time
less force, and less time
