Determine the objects velocity and position functions. Average speed = 400/5 = 80 kmph. Using the Pythagorean theorem, the resultant velocity can be calculated as, R 2 = (100 km/hr) 2 + (25 km/hr) 2. Momentum can be thought of as an object's ability to push another object due to its motion. Classically, momentum is defined as the mass of the object times the velocity of the object, p= mv. Since light has no mass, you may be tempted to say that light has no momentum. Additionally, everyday experiences may seem to confirm that light has no momentum (sunlight does not knock over soda bottles like baseballs do). Solution. Simple velocity vector problem; IS MY SOLUTION MANUAL WRONG OR AM I?! Focus on the Problem. This equation contains velocity, momentum and mass, so it can help in calculation of final velocity when mass and momentum is known. The viscosity of glycerine 1.5 Pa s.
