The ball falls downward and collides with the surface with a speed of 2.0 % The average force exerted during the collision is 20 N over atime interval of 0.1 s. Which of the following best predicts what will happen to the ball immediately after the collision? @ The ball will come to rest on the surface. The ball will bounce up from the surface with a speed lower than what it had before the collision. The ball will bounce up from the surface with the same speed as it had before the collision. @ The ball will bounce up from the surface with a speed greater than what it had before the collision. Question 24 3 - N Net Force (N) 2 3 4 Time (s) In an experiment, a variable net force is applied to an object. A graph of the net force exerted on the object as a function of time is shown. Which of the following experiments could have been conducted to represent the variable net force shown in the graph? A A 0.2 kg object increases its speed from 2 m/s to 8 m/s. B A 1 kg object increases its speed from 2 m /s to 4 m/s. C A 2 kg object increases its speed from 1 m/s to 3 m/s. D A 3 kg object increases its speed from 0 m /s to 1 m/s
