Question

Jonathan and Jane are sitting in a sleigh that is at rest onfrictionless ice. Jonathan's weight is 800 N, Jane's weight is 600N, and that of the sleigh is 1000 N. They see a poisonous spider onthe floor of the sleigh and immediately jump off. Jonathan jumps tothe left with a velocity of 6.00 m/s at 26.0° above thehorizontal (relative to the ice), and Jane jumps to the right at5.00 m/s at 38.8° above the horizontal (relative to the ice).Calculate the sleigh's horizontal velocity (magnitude anddirection) after they jump out.
??? m/s

Explanation / Answer

Momentum is conserved. Assume that the velocity of the sleigh headto the right. we have. 0=-800*6*cos26+1000*v+600*5*cos38,8 so v=2m/s v is positive so its direction is to the right
