Test practice problems, without answers

1. How high will a ball travel into the air, if thrown straight up at 25 m/s?

2. If this ball were thrown at a 40-degree angle (also at 25 m/s), find the following: time in air, horizontal displacement, max vertical displacement

3. Add the following vectors together, which are acting concurrently at a right angle to each other: 40 m/s and 60 m/s. Find the angle from the 40 m/s vector.
