Practice Questions
Question 1
A car is driving at $30 \, \text{m/s}$ north relative to the ground. A motorcycle is driving at $24 \, \text{m/s}$ north relative to the ground. What is the velocity of the car relative to the motorcycle?
Question 2
A plane is flying at $160 \, \text{m/s}$ east relative to the air. There is a wind blowing at $60 \, \text{m/s}$ north. What is the magnitude of the plane’s velocity relative to the ground?
Question 3
A train is moving at $50 \, \text{m/s}$ west relative to the ground. A passenger walks at $5 \, \text{m/s}$ west relative to the train. What is the passenger’s velocity relative to the ground?
Question 4
A cyclist rides at $10 \, \text{m/s}$ south relative to the ground. A pedestrian walks at $2 \, \text{m/s}$ south relative to the ground. What is the velocity of the cyclist relative to the pedestrian?
Question 5
A boat moves at $6 \, \text{m/s}$ east relative to the water. The water current flows at $4 \, \text{m/s}$ north. What is the magnitude of the boat’s velocity relative to the ground?
