Question

If m represent mass in kg, v represents speed in m/s and r represents radius in m show F in the formula F= (mv^2)/r can be expressed in the unit kg*m/s^2

Answer 1

m represent mass in kg
v represents speed in m/s
r represents radius in m

Now, just substitute these into the formula:

`F = (m* v^(2) )/(r) =(kg* ( (m)/(s) )^(2) )/(m) =(kg* (m^(2))/(s^(2)) )/(m) = (kg*m^(2))/(s^(2)*m ) =(kg*m)/(s^(2) )`
