Question

Make sure the cart magnets are facing each so that the action-reaction force between the carts is a force of repulsion. Give cart 1 an initial velocity (30 – 50 cm/s) toward cart 2 (initially at rest). Record the motion of each cart. V magnetic interaction 2 Velocity Curves Your velocity curves (v as a function of time) should have the following overall appearance: Velocity of Cart 2 Velocity of Cart 1 initial final Δνη Av2 final initial Δt At A velocity curve is divided into three distinct regions: 1. Constant Velocity (horizontal line) just before the interaction (initial). 2. Changing Velocity (steep sloping line) during the interaction (time interval At). 3. Constant Velocity (horizontal line) just after the interaction (final).

m1: 0.49 kg, 0.35m/s

m2:0.489 kg, 0.4m/s

Answer 1

Momentem chonge for cart I AP, = m, ovi = 0.49 x 0.35 - 0.1715 kgm/s For cart 2 OP = ma = 0.489 x 0.4 = 0.1956 kgm/s. So there is slight difference between momendrem last by one cont and momentum goined by other cart. second law neueton F = OP so Fiza AP, a 0.1715 at minus sign because veloclty is decreasing. at o 1956 - AP at N 21
