Answer :
The impulse one ball receives is equal to average force on it from the other ball multiplied by the time during which the force is applied
The impulse one ball receives is equal to average force on it from the other ball multiplied by the time during which the force is applied. By newton's third law the force that the rubber ball exerts on the steel ball is equal to the force that steel ball exerts on rubber ball. So the rubber ball receives the same amount of impulse , although the directions of impulse are opposite.
Jx = Fx Δt
Jx = Impulse acting on x
Fx = Average force acting on x ( Answer 1 )
Δt = Period of time
Jrubber = Frubber * Δt
Jsteel = Fsteel * Δt
According to Newton's third law,
Frubber = - F steel ( Answer 2 )
Jrubber = - Fsteel * Δt
Jrubber = - Jsteel ( Answer 3 and 4 )
Therefore, the answers are,
- Average
- Equal to
- The same
- Opposite
The given question is incomplete. The complete question is:
Suppose a rubber ball collides head-on with a more massive steel ball traveling in the opposite direction with equal speed. Which ball, if either, receives the larger impulse?
The impulse one ball receives is equal to the ___ force on it from the other ball multiplied by the time during which the force is applied. By Newton's third law the force that the rubber ball exerts on the steel ball is ___ the force the steel ball exerts on the rubber ball So the rubber ball receives ___ amount of impulse, although the directions of the impulses are ___
