Transverse pulses travel with a speed of 200 m/s along a taut copper wire whose diameter is 1.50 mm. what is the tension in the wire? (the density of copper is 8.92 g/cm3.)

So are u adding some additional catalyst

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.
