A dart gun is fired while being held horizontally at a height of 0.739 m above ground level, and at rest relative to the ground. The dart from the gun travels a horizontal distance of 6.61 m. A child holds the same gun in a horizontal position while sliding down a 35.3 ◦ incline at a constant speed of 2.36 m/s. 35.3 ◦ 2.36 m/s x x 1.54 m What horizontal distance x will the dart travel if the child fires the gun forward when it is 1.54 m above the ground? The acceleration due to gravity is 9.8 m/s 2 . Answer in units of m
