Projectile motion questions - thank you!?
1. A stone is thrown horizontally from the top of a 41 m hill. It strikes the ground at an angle of 11o. With what speed was it thrown?
2. A large cannon is fired from ground level over level ground at an angle of 79o above the horizontal. This initial speed is 993 m/s. Neglecting air resistance, how far will the projectile travel in the horizontal direction before striking the ground?
