A projectile is fired at a velocity of 100 m s-¹ at an angle of 36° to the horizontal as shown below. Calculate: 36° 100 m s-1 level ground a) the horizontal and vertical velocities of the projectile at the moment of firing b) the time after firing at which the projectile returns to the ground. c) the horizontal range of the projectile. Why is your answer likely to be an overestimate of the actual range?
