I'm having trouble figuring this one out. Hope someone can help A ball dropped from rest accelerates at a rate of 9.81 m/s2 if we ignore air resistance. If air resistance is not ignored, the ball reaches a terminal speed when the friction force of the air acting on the falling ball is equal to the gravitational force acting upon the ball. If, instead of being dropped, the ball is hurled upwards into the air at a speed greater than the terminal speed the acceleration of the ball is… a) 9.81 m/s2 b) less than 9.81 m/s2 c) greater than 9.81 m/s2 but less than 19.62 m/s2 d) 19.62 m/s2 or greater e) More information is required. I'm thinking you would need more information to actually pin down a number for the acceleration but I may be wrong. Would it be C, greater than g but less than 2g?
