In the following questions g = 10 m/s^{2} 1. A projectile has an initial velocity of 125 m/s.
2. The range of a projectile is 1500 metres with an initial velocity of 150 m/s.
3. A stone is thrown to clear a wall that is 4 metres high and 10 metres from the point of projection. If the angle of projection is 50^{o} calculate the initial velocity of the stone and the distance beyond the wall it strikes the ground. Assume that the stone is projected from ground level. Hint: Use the equation of the path of the projectile. Note that the point (10,4) lies on the path. |
