Question

Jonathan and Jane are sitting in a sleigh that is at rest on frictionless ice. Jonathan's weight is 850 N , Jane's weight is 550 N, and that of the sleigh is 950 N . They see a poisonous spider on the floor of the sleigh and immediately jump off. Jonathan jumps to the left with a velocity (relative to the ice) of 5.40 m/s at 30.0 degrees above the horizontal, and Jane jumps to the right at 6.50 m/s at 36.9 degrees above the horizontal (relative to the ice). A. Calculate the magnitude of the sleigh's horizontal velocity after they jump out. B. What is the direction of the sleigh's horizontal velocity after they jump out?

Explanation / Answer

u1x=-5.2*cos 30=-4.5 u2x=6 cos 36.9=4.8 so m1u1x +m2u2x=Mu so u=-1.78 m/s =1.78 m/s in left
