8. Lee is rolling along her 4.0-kg skateboard with a constant speed of 3.0 m/s when she jumps off the back and continues forward with a velocity of 2.0 m/s relative to the ground. This causes the skateboard to go flying forward with a speed of 15.5 m/s relative to the ground. What is Lee's mass?

Momentum is the product of mass and velocity. The principle of conservation of linear momentum states that the total momentum before collision is equal to the total momentum after collision.

Let the mass of Lee be m

Hence;

(4.0-kg × 3.0 m/s) + (m × 3.0 m/s) = (4.0-kg × 15.5 m/s) + (m × 2.0 m/s)

12 + 3m = 62 + 2m

12 - 62 = 2m - 3m

-50 = -m

m = 50 Kg
