Task For each problem below, create a I Sketch Qualitative description of motion {in words} Force diagram I freebody diagram Summed forces in both x and yr directions full solution [i.e. showing all stesz to the problem using appropriate notation and units. Assumptions assume the positive directions are upwards, fo rwards, to the right, N and E. upwardsI forwards, N and E are always drawn to the right. air resistance is negligible. the gravitational field strength on Earth, 9, is 3.8 ms2 and has 2 significant digits. SET 1 - Select 1 Problem to Submit Sample A horse pulls a 220 kg sled forwards. It starts from rest and reaches a final speed of 2.0 m/s over 3.0 m. Calculate the force the horse exerts on the sled. Neglect friction. Sketch Description of motion V1=0 V2 The sled speeds up from rest forwards.
