Tutor description

1. In the absence of air resistance, a ball of mass m is tossed upward to reach a height of 20 m. At the 10-m position, half way up, the net force on the ball is A. 2mg. B. mg. C.mg/2.D. mg/4. B is correct, as a vector diagram would show. Other choices show carelessness or confusion between force and speed, and what constant acceleration means.
