Rita's momentum is 294 kg.m/s.
What is momentum?The product of a particle's mass and velocity is called momentum. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum.
Given that Rita is riding a 7.0 kilogram bike at a velocity of 15 meters/second.
Mass of Rita = 42 kg.
Hence, her momentum is = mass × velocity
= 7.0 × 42 kg.m/s
= 294 kg.m/s.
Her momentum is 294 kg.m/s.
