A solide (S), of m=100g, is launched from the point O to moves up on an inclined plane by an angle a-30 with the horizontal. The motion of (S) is represented by the motion of its center of mass G on ox where i is a unit vector along this axis. At to-0, the speed of (S) is v=5i (m/s). The horizontale plane passing through O is taken as a gravitational potentiel energy reference. A- Frictional forces are negligible: 1. 1.1 The mechanical energy of the system (S-Earth) is conserved. Why? 1.2 Calculate the value of the ME at to-0. 2. After a certain time (S) is on M, such as OM-x, and its speed is v Determine in terms of x: 2.1 The expression of Gpe (the gravitational potentiel energy). 2.2 The expression of KE (kinetic energy). 2.3 Determine the position M, where the kinetic energy and the gravitational energy are equal.
