An ice skater with a mass of 50 kg is pushed across a level sheet of ice at 4.0 m/s^2 for 7 seconds. Calculate the net force that acts on the ice skater horizontally.​

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
