8.90 ⚫ Jonathan and Jane are sitting in a sleigh that is at rest on fric- tionless ice. Jonathan's weight is 800 N, Jane's weight is 600 N, and that of the sleigh is 1000 N. They see a poisonous spider on the floor of the sleigh and immediately jump off. Jonathan jumps to the left with a velocity of 5.00 m/s at 30.0° above the horizontal (relative to the ice), and Jane jumps to the right at 7.00 m/s at 36.9° above the horizontal (relative to the ice). Calculate the sleigh's horizontal velocity (magni- tude and direction) after they jump out.

A circus performer throws an apple toward a hoop held by a performer on a platform (Fig. P4.27). The thrower aims for the hoop and throws with a speed of 24 m/s. At the exact moment the thrower releases the apple, the other performer drops the hoop. The hoop falls straight down. a. At what height above the ground does the apple go through the hoop? b. If the performer on the platform did not drop the hoop, would the apple pass through it? Figure P4.27

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea.
