Question

MacGyver is riding on a skateboard and moving west of the velocity of 7 m/s. Macgyver has a mass of 92 kg and the skateboard has a mass of 8kg. if MacGyver jumps off the skateboard and velocity of 2 m/s east, What will the final velocity of the skateboard be? Show your work.

Answer 1

Answer:

64.5

Explanation:

(m1 + m2) v initial = (m1 * v1 final) + (m2 * v2 final)

(92 + 8)(-7) = (92 x 2) + (8 x v2 final)

(100)(-7) = (184) + (8 x v2 final)

-700 = (184) +  (8 x v2 final)

-516 =  (8 x v2 final)

-516/8 = v2 final

-64.5 = v2 final
