If a plate is dropped and comes in contact with a hard floor vs a playe coming in contact with a carpet, which has the greater impulse?
Answered by bobpursley
Impact is change momentum, or delta Velocity*mass. Don't they have the same change of velocity, and the same mass?

Denke.
Answered by Tri
Yeah, so therefor it is the same impulse?

but J = FT
The force is the same but the T interaction is different? or something?
Answered by bobpursley
If time of contact is different, then the forces are different. But implulse is the same.

thanks!

A small first-aid kit is dropped by a rock climber who is descending steadily at 0.5 m/s.
(a) After 2.6 s, what is the velocity of the first-aid kit?
