A firecracker in a coconut blows the coconut into three pieces. Twopieces of equal mass fly off south and west, perpendicular to eachother, at 18 . The third piece has twice the mass asthe other two.

Part 1
What is the speed of the third piece? (Answer in 2 sig figs andm/s)

Part 2
What is the direction of the third piece? (Answer in 2 sig figs anddegrees north of east)





--- piece one (west)
--- piece two (south)

Let m1 and m2 = m, and m3 = 2m






--- Two sig figs would be 13m/s

To find angle:

north of east.

A firework has been launched into the air and explodes into 3 pieces. Magically, the pieces explode in a two-dimensional plane parallel to the surface of the earth. A 75 gram piece flies off straight south at 23 m/s, a 25 gram piece flies off straight west at 13 m/s. If we knew the whole firework had a mass of 150 grams, what then is the speed and direction of the last piece?

A firecracker is placed inside a pumpkin. The pumpkin is slid along a frictionless horizontal surface at 5.82m/s. While the pumpkin is sliding it explodes into two pieces, one piece is twice as massive as the other. After the explosion, the larger piece is moving with three times the speed of the smaller piece. How fast is the larger plece moving? Give your answer in meters per second.
