i need help with both questions **Educational Physics Problem: Bullet and Block Dynamics****Situation:**A bullet of mass \( m \) is fired into a block of mass \( M \) that is initially at rest. After the bullet becomes embedded within the block, the combined system slides a distance \( d \) across a horizontal surface. The coefficient of kinetic friction between the block and the surface is \( \mu_k \).---**Part A:**Objective: Derive an expression to calculate the bullet's speed \( v_{\text{bullet}} \).- **Task:** Express your answer using the variables \( m \), \( M \), \( \mu_k \), \( d \), and necessary constants.- **Helpful Hint Available:** If needed, access the hint for assistance in formulating the expression.**Input Box for Expression:** [Equation-input interface]**Submit Button:** Upon completion, submit your derived expression.---**Part B:**Question: Calculate the speed of a 12 g bullet that is fired into a stationary wood block with a mass of 9.0 kg, where the block slides 4.4 cm across the table.- **Assumption:** The coefficient of kinetic friction \( \mu_k \) is 0.20.- **Note:** Provide your final answer with two significant figures and include the appropriate units.
