A police officer is driving due north at a constant speed of 26 m/s relative to the ground when she notices a truck on an east-west highway ahead of her, traveling west at high speed. She finds that the truck's speed relative to her car is 56 m/s (about 130 mph). On a sheet of paper, sketch the vector triangle that shows how the truck's velocity relative to the ground is related to the police car's velocity relative to the ground and to the truck's velocity relative to the police car. The sketch need not be to scale, but the velocity vectors should be oriented correctly and bear the appropriate labels. What is the truck's speed, relative to the ground? Number i Units

A police officer is driving due north at a constant speed of 26 m/s relative to the ground when she notices a truck on an east-west
highway ahead of her, traveling west at high speed. She finds that the truck's speed relative to her car is 56 m/s (about 130 mph). On a
sheet of paper, sketch the vector triangle that shows how the truck's velocity relative to the ground is related to the police car's
velocity relative to the ground and to the truck's velocity relative to the police car. The sketch need not be to scale, but the velocity
vectors should be oriented correctly and bear the appropriate labels. What is the truck's speed, relative to the ground?
