Question
Two girls decide to jump off a diving board. Katherine steps off the diving board. Anna runs off the diving board so that her initial velocity is solely horizontal. They both leave the diving board at the same time. Which one lands in the water first?Katherine, Anna, or both landing at the same time.
A juggler throws a ball with an initial horizontal velocity of +1.1 m/s and an initial vertical velocity of +5.7 m/s. What is its acceleration at the top of its flight path? Make sure to consider the sign when responding. Consider the upward direction as positive.
_______________ m/se2
Explanation / Answer
Two girls decide to jump off a diving board. Katherine steps off the diving board. Anna runs off the diving board so that her initial velocity is solely horizontal. They both leave the diving board at the same time. Which one lands in the water first?
Katherine, Anna, or both landing at the same time.
A juggler throws a ball with an initial horizontal velocity of +1.1 m/s and an initial vertical velocity of +5.7 m/s. What is its acceleration at the top of its flight path? Make sure to consider the sign when responding. Consider the upward direction as positive.
_______________ m/se2
For all projectile problems, the acceleration in the x-direction is always 0. In the y-direction, the acceleration of a projectile is always g, -9.8 m/s^2.
So the answer of your question is -9.8m/s^2 in the y-direction.
