Cart 1 has a mass of mi = 318 kg and an initial velocity of vol = 6.23 Cart 2 has a mass of m2 = 287 kg and an initial velocity of Vo2 = 4.57" Voi = 6.23 m/s Voz = 4.57 m/s 1 m = 318 kg m2 = 287 kg a) If the two carts collide in a purely inelastic collision, what is the final velocity of the two carts? (8 points) b) If we treat only Cart 1 as the system, what is the magnitude and direction of the impulse exerted on Cart 1 by Cart 2? (6 points) c) If we treat only Cart2 as the system, what is the magnitude and direction of the impulse exerted on Cart 1 by Cart 2?

Answer 1

a)

using conservation of momentum

m1 v1 + m2 v2 = ( m1 + m2) v.

318* 6.23 + 287* 4.57 = ( 287 + 318) v

v = 5.4425 m/s

b)

P1 = 318* ( 5.4425 - 6.23) = - 250.416 kg m/s

c)

P2 = 287* ( 5.4425 - 4.57) = 250.416 kg m/s
