A car with a momentum of 1200 kg. m/s with a mass of 600 kg hit a trash can which was on the side of the road, If the mass of trash can is 7 kg and the velocity of the car after the collision was 10 m/s, what will be the final velocity of the trash can ? What kind of collision this one is? Explain,

The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ =[2.90m+(0.0900m/s2)t2]i^− (0.0150m/s3)t3j^. a: at what value of t does the velocity vector of the insect make an angle of 34.0 degree clockwise from the x-axis? b: at the time calculated in part (a), what is the magnitude of the acceleration vector of the insect? c : at the time calculated in part (a), what is the direction of the acceleration vector of the insect?
