1) A small steel ball bearing with a mass of 20.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.17 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 26.0o from the horizontal.
2) A body pulled by a constant force accelerates from 10 cm/s to 20 cm/s in 3.5 s. A second force accelerates the same body from rest to 105 cm/s in 13.5 s. If the first force is known to be 4.5 N, that what is the second force?
