# A hockey puck struck by a hockey stick is given an initial speed \( v_i \) in the positive \( x \)-direction. The coefficient of kinetic friction between the ice and the puck is \( \mu_k \).

A hockey puck struck by a hockey stick is given an initial speed \( v_i \) in the positive \( x \)-direction. The coefficient of kinetic friction between the ice and the puck is \( \mu_k \).

**Part a)** Obtain an expression for the acceleration of the puck as it slides across the ice. *(3 points)*

**Part b)** Use the result of part (a) to obtain an expression for the distance \( d \) the puck slides. The answer should be in terms of the variables \( v_i \), \( \mu_k \), and \( g \) only. *(3 points)*
