Calculation of Resulting Velocity
a westward force of 20 N acts on a 2.0 kg object moving eastward at 60 m/s for 2.0 s. What is the resulting velocity?
1 answer
Draw a free body diagram with the force of 20N and with Fn and with fg and then find the acceleration with newton second law . When you find the acceleration you can plug it into kinematics equation : vf=vi+at to find final velocity
