The rising concern among athletic trainers regarding concussions among football players has prompted numerous studies of the effectiveness of protective head gears. One study suggests that concussions may result from impacts rated at 740 m/s2. If a player's head mass (with helmet) is 6.0 kg and considered to be a free body, then what net force would be required to produce an acceleration of 740 m/s2?
