33% Part (b) Ball A is thrown horizontally (i.e., the ball is moving parallel to the ground at the instant it leaves the person's hand) at a speed of 5 m/s. Define the +y-direction to be straight up (away from the ground) and the +x-direction to be the direction in which the ball was thrown. Which of the following must be true? Select all that apply. The initial value of the x-component of the ball's velocity is 5 m/s. Grade Summary Deductions 0% The initial value of the y-component of the ball's velocity is 5 m/s. Potential 100% The x-component of the ball's acceleration is -9.8 m/s2. Submissions The y-component of the ball's acceleration is -9.8 m/s2 Attempts remaining: 3 The y-component of the ball's acceleration is 0 m/s2.
