In the image below, a ball is thrown vertically upwards from the ground to a friend located at a window. You can neglect any air resistance. Use kinematics to do the following: (a) Calculate how fast the ball was thrown upwards if your friend catches it just as the ball stops moving. Instead, the ball is thrown upwards with a speed of 30 m/s. (b) If the friend does not catch the ball, calculate the time the ball is in the air from when it was first thrown until the friend sees the ball on the way down.

The following image shows a projectile being launched from a cliff. Use kinematics to do the following: (a) Calculate how far from the base of the cliff the projectile will land on the ground.(b) Calculate the speed of the projectile when it lands on the ground.(c) Calculate the maximum height above the ground reached by the projectile.

The graph below describes the motion of an object moving horizontally. All segments are curved, except for (EF) which is a straight line. For the following questions, express intervals using two letters (such as AB). The positive direction (+) points to the right. Then provide a very brief explanation why you are picking these intervals. If the vertical axis represents POSITION, identify all intervals: (a) when the object is moving to the left.(b) when the object is slowing down. If the vertical axis represents VELOCITY, identify all intervals: (c) when the object is moving to the right.
