The figure below shows the vertical velocity of the ball after it leaves your hand. Air resistance is not important. 12.0 6.0 60 -12.0 -18.0 1.0 20 3.0 1. Find the gravitational acceleration on planet X. You hit a golf ball into the air with an initial horizontal speed of 20 m/s and an initial vertical upward speed of 48 m/s on planet X. Neglect air resistance. 2. Find the maximum vertical displacement of the ball. 3. Find the horizontal displacement when the ball is at its maximum vertical displacement. 4. Find the speed of the ball when it is at its maximum vertical displacement. A rock is thrown from a 300 m high cliff with an initial horizontal speed of 30 m/s and an initial vertical speed of 0 m/s on Earth. Air resistance is not important. Use g = 10 m/s/s. 5. Find the time it takes the rock to hit the level…

Newton's Law Law. Which of the following scenarios demonstrates Newton's 2nd Law? O A planet exerts an attractive force on all objects on its surface. O A cyclist is launched forward when the bicycle is stopped by the corner of a side walk. O A person feels a push back when they push on a wall. O A box sliding on the floor slowly comes to a rest due to friction.
