Question 1 In ure praviced two suitcases are on 4 eo h ;h ramp to pe:52 ers waiting inbag ag: termnal. what is their combinec speed i-an inelastic colision is achieved? Assume the ramp to be trictione55. he top suitcase s ro eas20 rc restnd s des do n the ram and his t second uitcase. the suitcase at the top hasmass of1 5.0 kg and the otne suitcase has a mass a 30 kg B) 13 pellet is shot horizontaly rom a 0B un at a speec or 25.4 m/s into 205 ooden block. The ooden olock is attac ed to a spring and ies a rictio less table. ir the collision s inelastic and the spring (ons ant k 17.0 e n hat s the aximum con pression of the spring?

Explanation / Answer

1. speed of suitcase at the bottom of ramp,

applying energy conservation,

Pei + KEi = PEf + KEf

m g h + 0 = 0 + m v^2 / 2

v = sqrt(2 x 9.81 x 4) = 8.86 m/s

Applying momentum conservation for collision,

(15 x 8.86) + (30 x 0) = (15 + 30) v

v= 2.95 m/s
