20 points :) pls answer correctlyy A 70.0 kg skydiver has a weight of 686 N. Just before opening the parachute, they experience 300 N of air resistance. Use F = ma to determine how much are they currently accelerating?

9.8 m/s^2 down
7.6 m/s^2 down
5.5 m/s^2 down
3.8 m/s^2 down

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
