### Transcript

in order to calculate the impulse of the collision It's

like two answers right near the options All right well

in physics impulses the transfer of mo mentum from one

object to another Think of a game of pool when

we strike the cue ball with the stick there's a

transfer of mo mentum like here to here when the

cue ball strikes another ball well that's another transfer of

mo mentum each collision is an impulse where the force

of one object delivers momentum to another object over a

given period of time Impulses defined his force times the

change in time equation looks like this because we're good

physics students way know that force equals mass times acceleration

right We just know that And since we're great physics

students problem we know that acceleration equals velocity divided by

time Write a will overtake Now the force equation can

live like this force equals mass times the quotient of

velocity divided by time And while we're having fun with

equations that means that if we multiply both sides by

time we'll see that force times time equals mass times

velocity In other words the impulse of force times time

equals mo mentum and that means we don't need to

know the coefficient of friction of the surface The block

is sliding on and we also don't need to know

the kinetic energy of the block The options being dear

incorrect to things We need no r a the mass

of the block and see the change in its velocity

That's it way also need to know if the place
