Do this with the roller costar in class and the 25 mm (0.067 kg) ball in projectile launcher with spring constant (k) of 200 N/m If we start our system (the ball up the slope) with __(from above)_ m/s initial velocity and we assume friction is close to 0 N (no negative work done by friction [energy transferred to the surface by the force of friction), what distance up the slope will the ball reach if the angle of the slope is 38 degree? What height above 0 m (if we consider the ball leaving the spring launcher to be 0 m) will the ball reach?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
