To solve the problem step by step, we will analyze the motion of the particle before and after it strikes the smooth horizontal surface. ### Step 1: Identify the given data - Initial velocity of the particle, \( u = 100 \, \text{m/s} \) - Angle of incidence, \( \theta_1 = 45^\circ \) - Coefficient of restitution, \( e = 0.57 \) ### Step 2: Break down the initial velocity into components ...
