Magnitude of acceleration due to gravity, . Problem 1: A block of mass is initially held at a certain point on slippery incline of height that makes angle with the horizontal. The block is in contact with, but not attached to, a spring of stiffness, and compressed length, . The relaxed length, of the spring is also equal to the total length of the incline. When you release the block, the spring pushes it up all the way to the top of the incline, at which point it is launched into the air.

Energy princple, kinetic energy 1.2 What assumption(s)/approximation(s) do you need to make to better help you solve the problem? gravity is 10 m/s^2 friction and air resistance are negligible the spring is ideal 1.3 Identify your system (i.e. objects experiencing a change) and surroundings (i.e. objects causing the change). system-block surroudnings- earth, ramp, spring

Part 2: Predict the time, after it is launched, for the block to reach the highest point on its ±ight. 2.1 What principle(s)/concept(s) will you need to help solve the problem? momentum principle, kintenmatics 2.2 What assumption(s)/approximation(s) do you need to make to better help you solve the problem? gravity is 10 m/s^2 the spring is no longer in contact with the block air resitance is negligable projectile motion
