Simple interest depends on the principal (P), the rate (r), and the time (t). The equation for simple interest is given below,
I - Prt
The equation can be rearranged so that the principal can be determined if the other
variables are known. Move the options into the equation below to show the equation
solved for P.
P=

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
