    A cart traveling at 9.64 m/s (this movement defines the positive direction) has a head on elastic collision with a 24.1 kg cart traveling at 5.62 m/s. If the final velocity of the first cart is 7.007 m/s, what is it's mass?

    kg?

    A cart traveling at 5.97 m/s (this movement defines the positive direction) has a head on elastic collision with a 25.3 kg cart traveling at -1.4 m/s. If the final velocity of the first cart is -7.79 m/s, what is it's mass?

    kg?

    A cart traveling at 8.68 m/s (this movement defines the positive direction) has a head on elastic collision with a 11.7 kg cart traveling at 2.77 m/s. If the final velocity of the first cart is -2.563 m/s, what is it's mass?

    kg?

    A cart traveling at 8.86 m/s (this movement defines the positive direction) has a head on elastic collision with a 36 kg cart traveling at 0.86 m/s. If the final velocity of the first cart is -2.281 m/s, what is it's mass?

    kg?

    A cart traveling at 3.6 m/s (this movement defines the positive direction) has a head on elastic collision with a 35.8 kg cart traveling at 3.12 m/s. If the final velocity of the first cart is 2.844 m/s, what is it's mass?

    kg?

    A cart traveling at 2.8 m/s (this movement defines the positive direction) has a head on elastic collision with a 27.8 kg cart traveling at -0.77 m/s. If the final velocity of the first cart is -0.4593 m/s, what is it's mass?
