if the unit of power is the watt (W), and P = Fd/t, show using the result of question (2) and the fact that distance (d) uses units of meters and time has units of seconds.

*** question 2. If m represents mass in kg, v represents speed in m/s, and r represents radius in m, show that the force F in the question F = mv^2/r can be expressed in the unit kgm/s^2.

F=mv^2/r -----> kg(m/s)^2/m ---> kgm^2s^2/m = kgms^2
