A dart gun is ﬁred while being held horizontally at a height of 1.52 m above ground level, and at rest relative to the ground. The dart from the gun travels a horizontal distance of 7.81 m. A child holds the same gun in a horizontal position while sliding down a
35.7◦ incline at a constant speed of 0.807 m/s.
A.) What horizontal distance x will the dart travel if the child ﬁres the gun forward when it is 0.952 m above the ground? The acceleration due to gravity is 9.8 m/s^2. Answer in units of m
