A projectile is fired vertically with an initial velocity of 140 m/s. Calculate the maximum altitude h reached by the projectile and the ime t after firing for it to return to the ground. Neglect air resistance and take the gravitational acceleration to be constant at 9.81 m/s?. Answers: h = i t = i
