Polly ester and ray ahn are doing the elastic collision lab on a low-friction track. cart a has a mass of 1.00 kg and is moving rightward at 27.6 cm/s prior to the collision with cart b. cart b has a mass of 0.50 kg and is moving leftward with a speed of 42.9 cm/s. after the magnetic repulsion of the two carts, cart a is moving leftward at 10.1 cm/s. determine the post-collision speed and direction of cart b in cm/s. cm/s

32.5 cm/s

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

Let right direction be positive while left negative hence

1*27.6+(0.5*-42.9)=1*-10.1+0.5v

16.25=0.5v

v=16.25/0.5=32.5 cm/s in the right direction

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

answer; equivalent to a one(1) horsepower motor;
