(b) Consider the situation when friction force is non-zero. What is the expression for theacceleration of the cart now? (Use the following as necessary: m1, m2, f, and g.) 2)If you now triple the hanging mass m1, (so m= 3m1) how will the value of the denominator forthe expression for the acceleration change?What is the expression for the acceleration now? (Use the following as necessary: m1, m2, f, andg.) 2) Based on your answers to the previous parts, what conclusion can you draw about theacceleration of the cart?Additional Materials.
