Now, the target moved further away and the sniper must compensate, primarily adjusting the angle of its rifle. If the new angle is now 21° but everything remains the same (150m high building, 1800km/h initial velocity), which of the following solution will provide the time for the bullet to reach the maximum height? O (500cos21)/9.81 O (500sin21)/9.81 O (1800sin21)/9.81 O (1800cos21)/9.81
