What is the acceleration in (meters/second^2) of a free

What is the acceleration in (meters/second^2) of a free falling 72.0 kg sky-diver if air resistance exerts a force of 276 N.A wet bar of soap slides freely down a ramp 18.0 m long inclined at 86.0 degrees. How long (in seconds) does it take to reach the bottom? (neglect Friction)A 7.0 kg object moving with a constant velocity of 1.0 m/s is acted upon by a force of 16 N in the direction of the motion for 4.0 s. What is the velocity in (meters/second) of the object at the end of this time?A wooden box weighing 251 N is pushed across the floor by a workman who exerts a horizontal force of 173 N. If the force of friction between the box and the floor is 22 N what is the acceleration in (meter/second^2) of the box?
