PLEASE answer number 2 and 4 only. Read the direction to be guided. Show your step-by-step solution on how you get the answers. Thank you!

Directions: Solve on separate sheets and provide the calculated answer for the following described relative velocity problems: Write your answer under the third column (Magnitude). Problems Magnitude The motorboat is running upstream with a velocity of 65 kmyhr against the current that is 25 km/hr. What will be the motorboat's resultant velocity? 2 The fastest stunt man is running on top of each wagon against the direction of the train. The train is moving 20 miles per hour (mi/hr) towards East and the man at Its maximum speed is moving with same velocity of 20 mi/hr towards West. What is the man's velocity relative to the Earth? 3 What will happen to your velocity relative to the river banks or the shore if you walk across the boat that is moving downstream? 4 The river current is 15 km/hr, you are in a boat moving downstream with a velocity of 20 km/hr. You walk towards the front of the boat with a velocity of 5 km/hr, what is your resultant velocity relative to the river shore? 5 If an airplane is moving towards North with a velocity of 120 km/hr has encounter a headwind with a velocity of 40 km/hr, what will be its resultant velocity
