Anza has a mass of 59.1 kg. Ben has a mass of 53.9 kg. The cart has a mass of 26.7 kg. Anza, Ben, and the cart all started from rest (in the laboratory frame of reference). While Anza remained standing on the cart, Ben jumped to the right (just as was the case in the previous question). Ben jumped to the right with a speed of 3.5 m/s relative to the moving cart (so Anza would have seen Ben moving away from her with a speed of 3.5 m/s). Anza Ben VA VB Then (after Ben jumped to the right) Anza jumped to the left. Anza jumped with a horizontal speed of 3.3 m/s relative to the moving cart. In other words, after both Ben and Anza jumped, Anza would have seen the cart moving away from her with a speed of 3.3 meters per second. After Anza jumped, what was the velocity of the cart (in meters per second) in the laboratory reference frame? Consider the positive direction to point to the right. The sign of your answer (positive or negative) is important.
