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 â—¦ incline at a constant speed of 2.36 m/s. 35.3 â—¦ 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

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
