To find the dot product of the velocity and acceleration vectors, we multiply their corresponding components and sum the results. From the previous steps: The velocity vector is: v(t) = (1)/(2)(-((t)/(2))i + ((t)/(2))j) The acceleration vector is: a(t) = -(1)/(4)(((t)/(2))i + ((t)/(2))j) Step 1: Identify the components of each vector. For v(t): v_x = -(1)/(2)((t)/(2)) v_y = (1)/(2)((t)/(2)) For a(t): a_x = -(1)/(4)((t)/(2)) a_y = -(1)/(4)((t)/(2)) Step 2: Calculate the dot product v(t) · a(t) = v_x a_x + v_y a_y. v(t) · a(t) = (-(1)/(2)((t)/(2)))(-(1)/(4)((t)/(2))) + ((1)/(2)((t)/(2)))(-(1)/(4)((t)/(2))) Step 3: Simplify the expression. v(t) · a(t) = (1)/(8)((t)/(2))((t)/(2)) - (1)/(8)((t)/(2))((t)/(2)) v(t) · a(t) = 0 v(t) · a(t) = 0 What's next?
