10) The weight of an object can be described as the pull, or force, of gravity on it. This force is given by the mass of the
object times the acceleration due to gravity, F=mg. The acceleration due to gravity, g, is a constant with a value of
9.81 m/s?. Calculate the weight due to gravity in Newtons of an object that is 4.69 lbs.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
