Question

1. As a ball is thrown at an angle theta above the horizon, the x-component of velocity will decrease in magnitude, stop, then increase in magnitude again but with opposite sign. This statement is false, explain why with equations or logic.

2. If the velocity vector points to the right and the acceleration vector points to left, then the object will increase in magnitude. This is false. Explain why with equations, diagrams or logic.

3. If the acceleration of an object is 3 m/s/s. Then in one second of time, the change in velocity is ? , explain with equations or logic or diagram.
