The wind is blowing at 60 km/h from a bearing of 200. Find the groundspeed (the magnitude of the ground velocity) of the airplane. C4) 2. A weight lifter is holding a weight above his head which is exerting a force of approximately 2000 N straight down. His arms (extended) make an angle of 60 with one another. Determine the magnitude of the tension in each arm. (5) 3. The rope that pulls a sleigh makes an angle of 40 with the ground. A father pulls a child in the sleigh with a force of 75 N. How much of the force is being used to pull the child forward? @ 4. A rocket is fired at an angle of 25 to the ground and with an initial velocity of 120 m/s. Resolve the vector into its vertical and horizontal components and state the magnitudes of each component
