An empty can of mass 120g rests on top of a fire and explodes into three, fragments. One 30g fragment travels east at 60m/s and another 20g goes south at 100m/s. Calculate the velocity of the third piece.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

statement #3 on andre"s list is false.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
