MC8Q1 Points: 0/1 Ima Rilla Saari rushes to her car in order to hurry home and get dressed for work. Failing to realize the dangers of driving under slick and icy conditions, she collides her 980.0-kg Mazda Miata into the rear of a 3269.0-kg pick-up truck which was at rest at the light on Lake Avenue. Ima's pre-collision speed was 14.1 m/s. Determine the 3269.0- collision speed of the two entangled cars as they slide across the ice.

MC8Q5 Points: 0/1 The engineers are doing some car management at the train yard. A railroad car moving with a speed of 2.46 m/s collides and couples to a two-car combination that is moving in the same direction at 1.27 m/s. All cars have the same mass of 16000.0 kg. Determine the speed of the three coupled cars after the collision. Final Speed of Cars 1.71 m/s X Info Attempts: 1/co Submit SO Help Links Sa with Points: 1/1 of s 6. MC8Q6 HT- sou A 902-kg sports car is moving at 12.5 m/s when it rear-ends with a stopped car having an identical mass at a stop light. The two cars entangle and move together after the collision. What is their speed immediately after the collision? She Valid Info Attempts: 1/co Post-Collision Speed 6.25 m/s Submit Go Help Links Points: 1/17. MC8Q7 Points: 1/1 A 2.50-kg cart moving with an initial speed of 93.4 cm/s collides and sticks to a 2.00-kg cart initially at rest. Then the two carts continue in motion and collide with and stick to a 1.50-kg mass also at rest initially. Determine the post- collision speed (in cm/s) of the triple-cart system?

MC8Q8 Points: 0/1 In a Little Sticks hockey game at the community ice rink, a 0.103 kg hockey puck moving at 33.0 m/s is caught and held by a 40.5 kg goalie who is at rest. With what speed (in cm/s) does the goalie slide on the ice after the catch? S Final Speed 0.167 cm/s X Info Attempts: 1/0o Submit Sa wit of Help Links HT SO Sh 9. MC8Q9 Points: 1/1 Vali No student likes having to start a Minds On Physics mission over. And when Jack D. Ripper sees his Health Bar drop to 0%, he flings a 9.2-gram pencil across the room at 355.0 cm/s towards a 134.9-gram Sponge Bob doll at rest on his dresser. The pencil lodges into the doll and the two slide together across the dresser surface. What is the post- Go a piercing speed of the doll (and pencil)?
