It has been many years since physics 12 - I am helping my daughter. She and I will laugh in the morning over thinking that 2025 N does not equal 2.0x10 to the third when rounded. Many thanks...

ah ha it is becoming clearer. I appreciate you making me think.

haruspex said that was only the force of interest not the net force. Also 2025 N is not one of the options for an answer.

exactly what we thought - T cannot be zero as it wouldn't be doing any work. So then we thought T = net force on the object = ma = 810 kg x 2.5 m/s2 but that seems to be incorrect? Why?

ok so - tension is the force transmitted through the cord on the object. Force of gravity and normal upward force are equal so cancel out but we are trying figure out horizontal force not vertical force anyways. We are lost...

thanks

applied forces are: -2025 kgm/s2 from the parachute I have a feeling we are missing other applied forces.

sorry couldn't type subscript. It is the net force.

its an old nickname that came from a super friendly and never angry dog we had named zeena.
