Question

Quizplus · Accepted Answer

When a ball is tossed straight upward, it decelerates due to gravity (approximately 9.8 m/s^2) until it reaches the top of its path, where its velocity is momentarily 0 m/s. After reaching the top, it starts accelerating downwards due to gravity. One second after reaching the top, its speed would be 9.8 m/s, but since the options are in multiples of 10, the closest answer is 10 m/s (B).
