a high speed dart is shot from ground level with a speed of 140 m/s at a angle 30 degrees above the horizontal. 1. What is the speed& direction of the dart after 6 sec if the air resistance is neglected. 2. How high above the projection point is the ball after 6 seconds? 3. What is the horizontal displacement of the dart at that instance.

A particle is uncharged and is thrown vertically upward from ground level with a speed of...

A particle is uncharged and is thrown vertically upward from ground level with a speed of 23.1 m/s. As a result, it attains a maximum height h. The particle is then given a positive charge +q and reaches the same maximum height h when thrown vertically upward with a speed of 29.3 m/s. The electric potential at the height h exceeds the electric potential at ground level. Finally, the particle is given a negative charge -q. Ignoring air resistance, determine...
